Description Victor Vasilyev 2010-07-01 15:29:07 UTC 
If the -XX:+HeapDumpOnOutOfMemoryError option is not supported by the JVM, e.g. by the OpenJDK on the Fedora Linux, then there is annoying spam in the IDE log.

Proposed patch

To fix this issue the attached patch could be applied to the script
o.n.bootstrap/launcher/unix/nbexec 
It will redirect spam to the /dev/null.

It also redirects stderr where we have spam from JVM.
Comment 4 Jaroslav Tulach 2010-07-21 07:59:46 UTC 
OK, if you think the "&>" is correct and will work on all platforms, go on and integrate your change.
Comment 5 Antonin Nebuzelsky 2010-10-11 14:59:17 UTC 
I don't think &> is correct here. This format of redirection is mentioned only in the documentation of bash, while docs of sh do not mention it at all. 

2>&1 is what redirects stderr to where stdout is redirected. So, to me the current statement in nbexec is formally correct ( > /dev/null 2>&1 ).

Also I could not reproduce the reported problem with OpenJDK 6 on my ubuntu box. I don't see any "spam" in the output.
