In this case, the problem is in the Java regex engine but according to
<
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6393051> and the
related entries in the Java bug database some matches have exponential time
complexity, at least with the algorithms Java uses so this is not a bug
they intend to fix. (I don't know if there are other algorithms that can
handle such cases.)
An alternative for the particular case that seems not to cause the problem
is:
<xsl:variable name="regex">("[^"]*")+</xsl:variable>
