BaseTestCase.execJavaCmd() does not work with weme 6.2

                 Key: DERBY-4647
                 URL: https://issues.apache.org/jira/browse/DERBY-4647

            Priority: Minor

Spawning a java process with BaseTestCase.execJavaCmd() does not work with weme 6.2, I think
because the boot classpath does not get passed. This issue came up in DERBY-4179.  After this
issue is fixed, BootLockTest should be enabled for weme.

The error is actually
.JVMJ9VM011W Unable to load jclfoun10_24: The specified module could not be foun
JVMEXEX013E Internal VM error: Failed to create Java VM
JVMEXEX014I Run C:\cygwin\ibmsvn\ntsoftware\weme6.2\bin\j9.exe -help for usage

execJavaProcess does pick up the j9 executable but does not pass on the other settings.

This is how my script invokes the test with j9. It probably has a lot of legacy system properties
not needed, but I suppose execJavaCmd should just pass along all system properties, but I
don't know how it would get the bootclasspath. Perhaps -Dbootcp was a way to pass it on in
the old harness.

oftware/weme6.2/lib/jdbc.jar junit.textui.TestRunner org.apache.derbyTesting.fun

Otherwise, currently I think the method is only used in replication and network server, but
am not sure.
