  • What context path? Is this Tomcat or something? Give us a lot more detail about what you are doing. – greg-449 Aug 03 '18 at 09:27

as your eclipse's log, which is related to heap memory when you start your application.
You need to increase memory size for eclipse:
- Open eclipse.ini in the Eclipse installation directory.

.......
-vmargs
-Xms128m
-Xmx1024m
-XX:PermSize=128m
-XX:MaxPermSize=1024m

- Restart eclipse The bug will run away.
ps: For your application, you need to provide more information.

  • That changes the settings for Eclipse itself. It looks like the question is about running a program (possibly in Tomcat) - the settings for that are elsewhere. – greg-449 Aug 03 '18 at 09:26

    yep, but we only have simple console log, so base on what we was provided I think it will fix the bug – Mr Special Aug 03 '18 at 09:30
  • The console log is clearly not code running in Eclipse so no it won't fix it. – greg-449 Aug 03 '18 at 09:32
  • no, the error log is simply - java.lang.OutOfMemoryError: PermGen space. I strongly believe that it will fix the problem, then we need to resolve other problems – Mr Special Aug 03 '18 at 09:36
  • --launcher.XXMaxPermSize 2048M -showsplash org.eclipse.platform --launcher.XXMaxPermSize 2048m --launcher.defaultAction openFile --launcher.appendVmargs -vmargs -Dosgi.requiredJavaVersion=1.6 -Xms1024m -Xmx1024m It is my eclipse ini Memory Distribution , I never get this error . i do not know why am i getting this error ?? – Ravi Aug 05 '18 at 04:06
  • So I need more log - deleted all files in TOMCAT_HOME/logs folder - restart tomcat, then provide whole catanina.out file – Mr Special Aug 06 '18 at 01:54
