Rel_2_6_0_020

[Ridgeglider]

I have noticed occasional shutdowns of the 2.6 NBEclipse.
I'm changing the memory allocation in the NBEclipse shortcut. Will post observations. Changing to:
C:\nburn\NBEclipse\NBEclipse.exe -Xms512m -Xmx1024m -XX:MaxPermSize=512M
as described in the wiki:

http://wiki.embeddedethernet.com/Eclipse_Memory, which by the way appears to have a typo in RED:

"Open that file and find the settings for -Xms and -Xmx.
-Xms sets the intitial heap size used by Eclipse
-Xms (should be Xmx I think) sets the maximum size to which the Eclipse heap can grow."

On another note: I've noticed that 2.6 behaves a little oddly on the Win7 64 taskbar. I run NB eclipse from a shortcut (allowing it to run as administrator). The shortcut is on my taskbar. When most of these taskbar icons are pressed to run the associated program, the icon changes to a square shape indicating that the program is running. These squares 'tile' to indicate multiple windows of the associated app. In pre-Rel2.6 releases. NBEclipse worked this way. Now however, it creates an additional tile. It works, but it's a little odd.

That is strange about the taskbar issue you have. I am running 2.6.020 on Win7-64bit and it does not do that on mine.

Interesting... I see the taskbar behavior on two win7 64 PCs...?

You are right about the typo on the wiki but you (and everyone else) should feel free to just log in and correct things that are wrong, not to mention adding new topics. I subscribe to all pages I've written so I'll get notified of modifications and review them. I am happy that the wiki actually got read by somebody.

I discovered the problem with PermGen space just recently when using the standard Indigo release of Eclipse and tried to add/update software. I wasn't sure the problem existed in NBEclipse but sounds like it just takes longer to appear. I really think the default memory settings are too low considering how much memory most machines have and how important a stable development environment is. Plus I believe this PermGen issue is a work-around for an underlying JRE bug.

Under win 7 ultimate 64 running a 32 bit version of Indigo my task bar behaves properly.

Tod: I am still experiencing NB Eclipse 2.6 crashes even with the modified settings:
C:\nburn\NBEclipse\NBEclipse.exe -Xms512m -Xmx1024m -XX:MaxPermSize=512M

I ran for awhile w/o issue, but the projects I have open for the last few days seem to make it unstable, even when I pay attention to keeping unused project closed.

Any ideas??

Normally, I would expect the NBEclipse release to be the most stable for doing NB development. Since I'm having very good luck with the latest release of Indigo I would suggest you give it a try. Take the three plug-ins (I skipped the docs plug-in) and copy them from the NBEclipse plugins folder to the Indigo dropins folder.

I'm currently running JRE 1.7.0_05 from Oracle but I had no problems with 1.6.0_33 from Sun in case that matters. (At least make sure you're on 1.6 or later) Test your version at http://javatester.org/version.html. The 1.7.5 version was a June 12, 2012 release of the JRE from Oracle, and since I can never leave well enough alone and it was supposed to fix many bugs I'm trying it, but I don't have that many hours logged on it yet.

You can also check your error log to see if it has any hints. One way to get to the log from inside Eclipse (not sure about NBEclipse) is from the Help->About click the Installation Details button, go to the Configuration tab and click the View Error Log button at the bottom. I found the PermGen solution by searching StackOverflow for my error log messages.

Finally, since it just bit me in the butt and is fresh in my mind, have you run a good hard drive checker recently? ChkDsk does not count. I was having some strange problems and eventually SpinRite convinced me it was my hard drive. The move to a solid-state-drive is the best improvement to my laptop I've ever seen, not to mention all my Eclipse and Visual Studio problems went away.
