Hi, John...

As I understand this description, the newer version of the JVM just
has different defaults for the memory settings. All versions of the
JVM allow these settings to be changed on startup, generally through
command-line options.

For instance, "java -Xms1024m -Xmx2048m -Xss4m" would set the initial
heap size to 1GB, the maximum heap size to 2GB and the stack size to
4MB.

However, since Editor or PE start the JVM for you, you need to use the
javavmargs and/or javavmmemory options to specify your settings. I
recall there being some issues with where these need to be set so that
the settings are in place before the JVM is started (setting them too
late will be ineffective), especially since newer Arbortext versions
apparently tend to start the JVM earlier than in the past.
Unfortunately, I can't find the details, so if this seems to be a
problem, post back and maybe someone can shed some light.
