Is it possible that your Java installation is hosed?
It makes one wonder. Several web links at IBM say to contact your service provider about message ID "JVMJ9VM020". And that's about it! IBM i 7.1 has been available for quite a while. One would think that others would have run into this problem.
On the other hand, the Java class runs fine and produces expected results when run through qsh. System i Navigator and other IBM i administrative interfaces use Java extensively, and they're working fine. The box is a new 720. I downloaded and installed CUME PTFs. The only problem seems to be with the RPG => Java interface.
But, since you appear to be pointing at jdk60, I guess that isn't a problem for you?
qsh reports:
java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build pap3260sr10-20111208_01(SR10))
IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 OS/400 ppc-32 jvmap3260sr10-201112

I used the same environment variables that you mention (JAVA_HOME, CLASSPATH, and QIBM_RPG_JAVA_PROPERTIES)
One problem is that I can't find any references that say what to set those environment variables to under 7.1 I finally decided to set JAVA_HOME to '/QOpenSys/QIBM/ProdData/JavaVM/jdk60/32bit', just prior to calling the RPG program. The Job Log indicates that a JVM starts. Then errors out.
I didn't have to do anything differently at 7.1...
That's kind of reassuring, but still a PUZZLEMENT.
Thanks,
