Uwe Schindler updated LUCENE-3537:
----------------------------------
Description:
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="http://www.oracle.com/technetwork/java/javase/7u1-relnotes-507962.html";>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="http://www.oracle.com/technetwork/java/javase/6u29-relnotes-507960.html";>Java
6u29</a>
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
unicode
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>

I plan to commit this later this afternoon.
