MyRobotLab
Make it easy and well documented to increase the heap size for MRL.
currently the only way to do this is with some magic args "-jvm" that seem to be completely lacking of any documentation and it's not normal for a standard java application that you would pass something like -Xmx or -Xms values on the command line.
we should make mrl easy to increase the heap size with something like a "-m 1g" sort of command line argument to specify the memory to give Runtime.
its supposed to already be documented in that its any or all pre-existing jvm flags .. perhaps it would have been "more" standard to be called java_opts
It's supposed to be any flags you may want e.g:
-jvm "-Xms64M -Xmx1g -verbosegc -Xns10m -Xgc: parallel"
all the flags "should" be relayed ... at least that's how I thought it worked ;)
I'm trying the following:
java -jar myrobotlab.jar -jvm "-Xmx256m" -service runtime Runtime python Python gui SwingGui -invoke python execFile /home/pi/github/pyrobotlab/home/kwatters/Harry.py
basically when I specify the -jvm arg.. runtime just dies and there's no details as to why.
Here's the no worky.. my eyes aren't working..

I feel that something like setting the heap size is such a desired thing, it should have it's own command line arg... i propose "-m" for memory...
