Do you mean that after you manually started the JVM, then the first
method call after that took 15+ seconds but subsequent calls were
faster?  I would have expected the "start JVM" part to take 15+ seconds
and then all method calls to be relatively fast.

I don't think there is any way to speed up the starting of the JVM.

JDK 1.4 should be fine with OS400_JVM_12.  The Java invocation API
changed between JDK 1.1 and 1.2, but it's still the same as the 1.2 JDK
for all subsequent JDKs; by defining OS400_JVM_12 you are just saying
you are using the newer form of the invocation API.
