Howard M. Lewis Ship closed TAPESTRY-1658.
------------------------------------------
Resolution: Cannot Reproduce
Assignee: Howard M. Lewis Ship
The code in question is ThreadLocal.get(); it's not out of the realm of
possiblity that the class' initialValue() method is the culprit, but based on
that stack trace, I don't think so.
Please re-open if this problem recurs. Generally speaking, when you say that's
there's a JDK or JVM bug, especially in something this fundamental, you're
usually wrong ... but in this case, there's so little for Tapestry to get wrong
that I don't see a viable alternative to a JDK bug.

> Key: TAPESTRY-1658
> URL: https://issues.apache.org/jira/browse/TAPESTRY-1658
> Project: Tapestry
> Issue Type: Bug
> Affects Versions: 5.0.5
> Environment: Sun's java 1.5_12, debian linux, tomcat 4.0.3
> Reporter: Robert Zeigler
> Assignee: Howard M. Lewis Ship
>
> I've started (sporadically) receiving the following error. Seems to hit
> after a period of inactivity? (Maybe?)
> But I also just upgraded the java version from 1.5_09 to 1.5_12 yesterday, so
> this may be a jvm bug.
> I'll see if downgrading solves the issue (but hard to know since the issue is
> so sporadic).
