Originally intent was to stress buffer resize code paths in debug builds,
but probably not needed anymore, you are right. I removed the
debug-specific size.

Done, now maps to guarantee()

Good idea, though misc_aix.hpp would not be the right place. That file is
specifically for stubs to SAP infrastructure coding which we do not want
(yet) to completely port to the OpenJDK.

porting_aix.hpp would be the right place for this.

But I rather do this in a speparate change.
