Extra -Xms and -Xmx javaOpts.

[paddymahoney]

Sbt native packager version: 0.7.0-RC3
We are using the java server archetype.
Our java opts are set within src/templates/etc-default like follows:
-J-Xmx4096m
-J-Xms1024m
-J-XX:MaxPermSize=1024m
-J-Xss2m
-J-XX:+UseCodeCacheFlushing
-J-XX:ReservedCodeCacheSize=128m
-J-XX:+CMSClassUnloadingEnabled

When the start script is then run with the -d param as follows:
$> /usr/share//bin/ -d

the output looks like:

Executing command line:

java
-Xms1024m
-Xmx1024m
-XX:ReservedCodeCacheSize=128m
-Xmx4096m
-Xms1024m
-XX:MaxPermSize=1024m
-Xss2m
-XX:+UseCodeCacheFlushing
-XX:ReservedCodeCacheSize=128m
-XX:+CMSClassUnloadingEnabled

My question is, where are the top three javaOpts being sourced from, and how can they be removed when etc-default is being used to supply the values for those params? While the heap min and max do take on the values that we supply in etc-default rather than the topmost ones, our ops people are concerned by the duplication.

Thank you sbt native packager team!

They come from the -mem options and they SHOULD be disabled when you pass in valid ones. This may be a bug.

This is a bug and already reported in #211
I think this is a problem in the bash script, which doesn't check properly on the -X options. If you use -mem it works correctly. However the -mem generates something like -Xms4096m -Xmx4096m.

The other option would be to override the bash-script (or provide a fix in a PR :) ).

I will look to fixing this in a PR at some point(unfortunately it looks
like I'll need to fix this on my own time). Is there an sbt-native-packager
dev mailing list or irc? Thank you for your responses.
