FYI: OutOfMemoryError

[Martin Trummer <ma...@24act.com>]

I just had a strange situation:
 * when I look at a project in the 'Project Group Summary', I see that
the last build was successful (the green sign)
 * then I open 'Build results' for that project and also see that the
last build was successful (the green sign)
   but when I now open the 'Result' for this build, I see the
errormessage/stacktrace below

My explanation/solution for this:
 * First I thought, that maven didn't have enough memory and messed
around with MAVEN_OPTS, but that was not the problem
   * after the automatic build, the target directory existed and the
.jar file was also there
   * and also manually calling maven (with the same arguments) on the
command line worked
   * so the maven build was ok & thus the green sign was also correct
 * when doing the manuall build I noticed, that my debug-level was very
low and that a lot of info was printed on stdout/stderr 
 * so I guess that:
   * the build was ok, but the problem only occured when the continuum
webapplication tried to render the build-results

solution:
increase the memory for the continuum web-application in:
C:\Programme\apache-continuum-1.2\conf\wrapper.conf
***
# Initial Java Heap Size (in MB)
wrapper.java.initmemory=256

# Maximum Java Heap Size (in MB)
wrapper.java.maxmemory=1024
***

now everything works fine again

cheers, martin
