How to know in which version a java bug was fixed
<p>I am trying to workaround the following bug:
<a href="http://bugs.sun.com/view_bug.do?bug_id=7019384" rel="nofollow">http://bugs.sun.com/view_bug.do?bug_id=7019384</a></p>

<p>in the bug DB the status is closed and the fix version is 7(b138).
How can I know if my version which is 7u21 contains the fix?</p>

<p>Thanks.</p>
