If the problem is in Ant's own process, set the ANT_OPTS env variable to
the options.
export ANT_OPTS="-XX:+HeapDumpOnOutOfMemoryError"
on unix or cygwin
set ANT_OPTS="-XX:+HeapDumpOnOutOfMemoryError"
on windows.
That's exactly what I did, but from whatever reason I thought that putting it to
.antrc file in my windows home dir (C:\Documents and Settings\...) would work,
but for windows the file is called antrc_pre.bat. But still seem to have some
problem with it, ant.bat refers to the file as %HOME%\antrc_pre.bat, but in fact
it doesn't work on my WinXP box, it needs to be changed to
%SYSTEMDRIVE%\%HOMEPATH%\antrc_pre.bat and it works OK.
