Re: How to set default Java version for the system to one different from IBM's default

We do set this properties environment variable without the java.version property - I think you need to get that out of there - it's at least of no use for you, as stated here in the 7.1 Release--to-release compatibility article in knowledge center's IBM Developer Kit for Java section":

* The Java system property,java.version, is not recognized as an
input property for the IBM Technology for Java JVM. In prior
releases, the Classic JVM was available which honored
thejava.versionJava system property as input for determining which
JDK to use. Beginning inIBM i7.1, the IBM Technology for Java is
the only available JVM and it requires the environment variable
JAVA_HOME to be specified to determine which JDK to use

There is also a warning about using java.version with the new JDK, in the IBM Support article, "Changing Default Version for JDK (java.version.) at http://www-01.ibm.com/support/docview.wss?uid=nas8N1017748

*Note:*You should not use the java.home system property to set the JDK home. This will not work on IBM i. In fact, if you attempt to set java.home in the SystemDefault.properties file, the Java product may stop working completely.

That's not a pretty possibility, is it!!

We set it manually as follows. Looking at this now, I see we
really need to change this for a more recent version of the JVM. ;-)


ADDENVVAR ENVVAR(QIBM_RPG_JAVA_PROPERTIES)
VALUE('-Djava.version=1.6;-Djava.awt.headless=true
