can't set -Xmx properly

[darmbrust]

Trying to set the memory limits via -Xmx4G, and finding that I can't, because it is always putting in its own value (why would this be hardcoded?)

[INFO] Execute:Java13CommandLauncher: Executing '/opt/java/jdk_x64_1.8.0_65/jre/bin/java' with arguments:
'-cp'
''
'-cp'
'/mnt/STORAGE/repository/org/jruby/jruby-complete/9.0.4.0/jruby-complete-9.0.4.0.jar'
'-Xmx384m'
'-Xmx4G'

where did the 384m come from?

The plugin shouldn't specify any max at all by default, just let the JVM select... it will do a much better job than 384m.

oops, filed issue in wrong project. Moved here torquebox/jruby9-maven-plugins#2

Ahh, found the issue. It doesn't check for memory values specified with a G.

The problem is actually in this project. Would suggest checking for either m or G - and/or don't specify a default at all - just let the JVM pick a reasonable default which is likely to be much bigger than 384m these days.
