MyEclipse: MyEclipse for Windows 7 64Bits

Post subject: MyEclipse for Windows 7 64Bits

Soon or later, all pc's will be using 64bits SOs even Windows and after some declarations from some MS employee, it's not far the day that we'll have 128bits SO.
So why not start now providing MyEclipse 64 bits compilations?
I'm using 64bits SO for some time already and now with Windows 7 64bits, I can see one lack of Win 64 bits, aplications.
Do you have any idea of when should MyEclipse have available one 64bits version ? I think that this necessity will only grow up from now.
Thanks

kvillaca ,
A 64-bit version for WIndows is absolutely planned, we will likely release it soon after our 8.0 GA release goes out or with 8.1 -- we haven't ironed out the final QA for that release yet, but it's definitely coming

Please make it available "soon after 8.0 GA release", rather than "with 8.1". Anxiously awaiting 64-bit .....

I'm waiting for it, too. I was expecting to be able to install (via the update site) on top of Eclipse 3.5.1 64-bit, but I can't. I guess I have to install a 32-bit version of Eclipse while I wait...

Matt,
What is the error message that you are running into? We have had users who have been able to work on 64 bit Windows 7 without issues in the past.

Hi Nipun,

I guess there are too many bit distinctions at play here. ;) I'm not having problems installing or running MyEclipse 8 on Windows 7 64-bit, as long as I install on top of the 32-bit version of Eclipse 3.5.1. If I try to install on top of the 64-bit version of Eclipse, I do get error messages. I'll retry the process sometime today and add a description of the error message if that's helpful.

Thanks,
Matt

I'm look forward to having the native 64bits release too.

Hi Nipun,

Here's the text from the error details panel:
Cannot complete the install because one or more required items could not be found.

and here is a screenshot of the same thing:

It looks like MyEclipse is looking specifically for the 32 bit version of Mozilla XULRunner. I guess it's possible that I could install only some of the MyEclipse 8 features as a way to dodge this OSGI requirement. Any thoughts?

Thanks,
Matt

Matt,
There is no 64-bit build of MyEclipse for Windows and thats the reason you are running into this issue. We only have a 32-bit and Im not sure if disabling certain features will help here.

Hi Nipun,

Seems like we're going in circles on this... That's why I said, "I'm waiting for it, too... I guess I have to install a 32-bit version of Eclipse while I wait." on December 9 above. I meant I'm waiting for a 64-bit version of MyEclipse for Windows 7. Isn't that what this whole thread is about? I only provided provided the error message because you said, "We have had users who have been able to work on 64 bit Windows 7 without issues in the past."

Michael,

Beyond just supporting the 64 bit version of Eclipse, we do have some other technical issues with a few features that could cause problems running in that version of Eclipse, which is why it's not just a slam dunk deal.

Support for this is not planned in 8.5, but I will look into this and see what I can do, I realize it would be good to have a "true" 64 bit version. I will update this thread as more details become available. Sorry for the inconvenience.

Brian,

I understand there are some technical hurdles. A true 64-bit version would be great. I won't be using MyEclipse until that happens, as I don't want to have two versions of Eclipse on my system, and Netbeans does just fine for now. Thanks for the update.

Hm, It's not quite clear to me what or how a 64 bit version of MyEclipse would benefit me. I've been using x64 versions of Windows Vista and 7 for over 2 years now, because of the opportunity to run several virtual machine side by side with VMWare, but I can't imagine advantages for ME. Could someone please give some explanations or reasons for this requirement a.k.a. demand?

TIA

The major benefit of using 64bit application is the memory addressing. But it is not for everyone.

I am personally haven't use the 64bit of eclipse since myeclipse doesn't support it under windows so far.
However, I am working on a project that has Tens of Thousands java classes. For which, even in the ant build script, I have to increase the max memory heap size to 1GB to compile them, otherwise, the compilation will run OOM. I can imagine that if the whole source files were added to eclipse with myeclipse plugin, it will eventually run out of memory too. Since the 32bit of OS only support 4GB memory (max, for most cases it is less since hardware will use some of the resource too). And this is the not the max memory any application can use, the truth is for single process under 32bit windows, the total amount of memory that can be addressed is less than 2GB.

For some people who is developing a huge project in myeclipse could eventually hit the memory limitation and the only possible solutions are 1, split the project into multiple smaller ones or 2, switch to 64bit IDE.

We are one of those cases (big projects causing issues with MyEclipse in a 32-bit JVM). Our project is so large that we actually push a 32-bit JVM to its limit. We have 75 projects, 23,000 files (10,000 Java source files, 7,200 JSPs). With bin and .svn folders, quadrouple this number to over 100k files.

We allocate 1024m of heap, and that's barely enough (not enough for everything in fact, the FindBugs validator will run it out of heap if we do a full validation). However, we can't go much larger than that because then we start running out of native memory or some other non-heap memory resource. When you increase the heap size, you're squeezing everything else out. MyEclipse (at least with our projects in it) is very unstable beyond 1024m heap (i.e. when a native call to allocate memory fails, MyEclipse dies pretty spectacularly). The 1024 is a balance between not running out of heap and not running out of some other non-heap memory resouse. A smaller heap and it runs out of heap. A larger heap and the frequency of the crashes from running out of some other non-heap memory resource go up dramatically.

We absolutely need the 64-bit version of MyEclipse 8 (i.e. MyEclipse running on Eclipse for 64-bit running on a 64-bit JVM). We were so looking forward to this. The last I checked this thread the response was "we'll support 64-bit JVMs in the first patch right after the 8.0 release", to now "not even planned for 8.5". That's very dissapointing. The productivity loss we have to endure from only being able to do a 1024m heap (lots of GC wait and freezes during heavy GC/load), as well as the instability from the IDE crashing all the time (either out of heap, or out of some other non-heap memory resource) is a real drag. It is a substantial loss of productivity for our whole organization.

Here's +70 votes for the 64-bit JVM and large heap support for MyEclipse in the near future.

Can't agree more. 64-bit is a must have for us.

Maybe you could give the community some idea of what these hurdles are and see how we can help? Long shot perhaps, but maybe the features are not even important enough to justify holding back a 64-bit release where those are just not available?

hi,
I agree with you guys that 64bits is gonna be important in coming development.
Just hope it is available after 8.5 release.
