> Oracle confirmed, that the bugs leading to index corruption and SIGSEGV are fixed in
Java 7u1 and 6u29. We should post a message to the news sections revising the previous WARNING
(LUCENE-3349). I prepared something, please comment before i commit:

> <section><title>26 October 2011 - Java 7u1 fixes index corruption and crash
bugs in Apache Lucene Core and Apache Solr</title>
> <p>Oracle released <a href="">Java
7u1</a> on October 19.
> According to the release notes and tests done by the Lucene committers, all bugs reported
on July 28 are fixed in this release,
> so code using Porter stemmer no longer crashes with <code>SIGSEGV</code>.
We were not able to experience any index corruption anymore,
> so it is safe to use Java 7u1 with Lucene Core and Solr.</p>
> <p>On the same day, Oracle released <a href="">Java
> fixing the same problems occurring with Java 6, if the JVM switches <code>-XX:+AggressiveOpts</code>
> or <code>-XX:+OptimizeStringConcat</code> were used. Of course, you should
<strong>not</strong> use experimental JVM options like
> <code>-XX:+AggressiveOpts</code> in production environments! We recommend
everybody to upgrade to this latest version 6u29.</p>
> <p>In case you upgrade to Java 7, remember that you may have to reindex, as the
> version shipped with Java 7 changed and tokenization behaves differently
> (e.g. lowercasing). For more information, read <code>JRE_VERSION_MIGRATION.txt</code>
> in your distribution package!</p>
> </section>
> {code}
> I plan to commit this later this afternoon.
