RE: Performance when using POI to create an excel workbook.

According to people who are a lot smarter than me, CRTJVAPGM is deprecated
in favor of the JIT compiler, especially in later releases of the JVM.  It
seems that the JIT compiler can do a better job of optimization based on the
actual usage of a piece of code than CRTJVAPGM can, since the latter is
based solely on static information.  This has evidently been the case since
about V5R1 or V5R2.

Don't hold me to that, though.  I haven't run any benchmarks to identify
which might be faster.  It's worth a shot, and as Scott says, let us know
what happens.
