Just to be in the clear. The java.home property is told to be "output only"
in the V6R1 documentation
(http://pic.dhe.ibm.com/infocenter/iseries/v6r1m0/topic/rzaha/sysprop2.htm)
and also in the V7R1 (checked in the PDF).

Does this mean that this is unsupported behavior that just happens to work,
or has this been added since the documentation was written?

It would help us a lot if this was a supported feature.

Remember that the J9 JVM's only recognize the version from whatever the
JAVA_HOME environment variable contains. In truth, it's the java command in
qshell that does the version selection and after V6R1, it no longer pays any
attention to the java.version set in the command line. There are several
ways to set JAVA_HOME. One is the SystemDefault.Properties file as you
discovered. The SystemDefault.properties file in your home directory is high
in the precedence list and will override whatever was in JAVA_HOME before
the call to the java command.

Notice that there's a symlink at /QIBM/ProdData/Java that points to
/QOpenSys/QIBM/ProdData/JavaVM to make older JAVA_HOME settings work.

I figured out the problem ... I had a SystemDefault.properties file in
my home directory and it contained:
java.home=java.home=/QOpenSys/QIBM/ProdData/JavaVM/jdk50/32bit

(not a typo in the email, thatis 'java.home=java.home...'

Which, apparently, causes Java all sorts of problems.
