Experimenting a little bit more, I was able to get more debug information by
changing the script's test to :
if ! $basedir/bin/java -client -Xshare:dump $xmarg -XX:PermSize=128m >
$log 2>&1; then
cat $log
rm -f $log
exit 1
fi
Then, I can now see it says :
Setting up sun-java5-bin (1.5.0-16-2) ...
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
dpkg: error processing sun-java5-bin (--configure):
subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
sun-java5-bin
So there's obviously something too limited with memory here ?
Hope this helps.
