Using IBM's Java is not recommended at all, for Solr or Heliosearch.
They enable many optimizations by default that are known to cause bugs
with Lucene and Solr.  Lucene has uncovered bugs with all JVMs, but the
bugs in IBM's Java are particularly persistent, and IBM seems to have
little interest in learning about them or fixing them.  The project does
have a good relationship with Oracle for problems in their code, so that
is the recommended implementation.

Lucene Revolution has happened in Europe.  In 2013, it was in Dublin.  I
don't have any information on the 2015 location.  There is also
something called Lucene EuroCon, but I can find no information about a
new event.  ApacheCon is another possibility, and the 2014 EU conference
was in Budapest.

Thanks,
Shawn
