compressed pointer in hotspot

[Xin Tong]

one of the idea i am currently evaluating for potential research is using
hardware performance counters to identify frequently accessed field and
make them uncompressed ( save the decoding and encoding cost) and leave the
other compressed.

Any suggestions.

Thanks

Xin
