RE: Signature mismatch when calling java prototype

["Gary L Peskin" <garyp@xxxxxxxxxxxx>]

Sorry for the confusion.  I didn't mean to invoke the RPG program itself
statically.  I meant that in this incarnation of the RPG program (the one
that produced the RNX0301), do you specify static in your PR definition spec
for the Java method.
