[TRAFODION-2682] JVM startup options like heap are not passed correctly
Character arrays used to build the options went out of scope before
they were passed to the JNI layer to create the JVM.
Selva also requested that we use the default heap size defined in
our code instead of the JVM default method of 1/4 the physical
memory when a value <= 0 is passed in env var JVM_MAX_HEA_SIZE_MB.

> Selva just found out that we don't pass the -Xmx option to the JVM when
> creating it in the executor. This is due to a bug in the change I made for
> TRAFODION-2637. I put character array variables into a local scope where I
> shouldn't have done that.
