For Java 6, the Sun JDK is the reference implementation.  For Java 7,
OpenJDK is the reference implementation.

http://en.wikipedia.org/wiki/Reference_implementation

I don't think Oracle's version could really be called slow.  Sun
invented Java.  Sun open sourced Java.  Oracle bought Sun.

The Oracle implemetation is likely more conservative than some of the
other implementations, like the one by IBM.  The IBM implementation is
pretty aggressive with optimization, so aggressive that Solr and Lucene
have a history of revealing bugs that only exist in that implementation.

Thanks,
Shawn
