OutOfMemory PermGen in STS 2.2.0 release

[get_it_done]

I have been trying to resolve the OutOfMemory PermGen issue that I have run into in STS 2.2.0 release


My application has been built on JDK1.6 , OPEN JPA, Spring 3.0 with Oracle backend.

The problem I face is that my application runs out of the PermGen every time I run my Junits. Specifically, it hangs in the middle of running junits throwing up java.lang.OutOfMemoryError: PermGen space

The Junit test relies on Spring heavily. All our Junits extend AbstractJpaTests.




the JVM options I am using are in the STS .ini file :
=====================
--vm
D:/proj/jdk1.6.0_12/bin/javaw.exe
-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v2009071 5.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.2 00.v20090519
-product
com.springsource.sts.ide
--launcher.XXMaxPermSize
256M
-showsplash
com.springsource.sts
--launcher.XXMaxPermSize
256m
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx1024m

=====================================

I have tried a few suggestions that I found on various forums -

Current STS .ini file in the installatin directory
Min and Max JVM heap size is set to 40 and 1024m

Updated them to 265 and 2048m
Closed and restarted the STS eclipse, wont even start


Kindly provide any pointers.

Hi,

it seems that your STS.ini is missing the following setting:

-XX:MaxPermSize=256m

Please add this to the end of the STS.ini.

Alternatively you could download STS 2.3.2 which has this setting out of the box.

HI Christian

I see this in the .ini file

--launcher.XXMaxPermSize
256M

Is it different from what you have suggested? Where exactly should I add it in my .ini file.

[Christian Dupuis]

yes, this is different. Please add the setting to the end of the ini file.
