Subject Re: Review Request: Add the dependence library (JNA) for maven exec:java goal
Date Thu, 18 Oct 2012 02:40:06 GMT
I forgot that installing agent.properties in the procedure.
It needs to be installed in advance to CLASSPATH directory.
KVM Agent is ended before the exception will occur, if we forget it.
