ZenFoundation's include-section macro crashes JVM when used with unexisting page

The following makes our JVM crash with no specific log messages

<ac:macro ac:name="include-section">
      <ac:parameter ac:name="page">Some unexisting page</ac:parameter>
    </ac:macro>

It is possible to reproduce this using the macro browser tool, too. We started seeing this after deleting a page used in this macro. As it stands, I can't even be sure if that's the only macro showing this behavior.

Is there anything I can do, other than disable the macro ? Have others seen the same problem ? Do I have any other choice than try all macros for possibly similar behavior ?

java version "1.6.0_32"

Java(TM) SE Runtime Environment (build 1.6.0_32-b05)

Java HotSpot(TM) 64-Bit Server VM (build 20.7-b02, mixed mode)

Yikes! Thanks for posting this, Gregory. We're on it, and will have this fixed for Zen 5.2.9.

Update: we have found and fixed the problem.

We will review all Zen macros to make sure this isn't a problem anywhere else, and will post anything else we find.

Thanks for the quick reaction. I'm curious what this stack overflow in CharsetDecoder could be.

Any ETA for 5.2.9 yet ?

No hard date set, but we're aiming for the next 3-4 weeks.

After updating to 1.6.0_45, the JVM stopped crashing, and we now see this, which confirms my suspicion that this was similar to CONF-15247:

which is then followed by

	at net.sf.hibernate.impl.SessionImpl.initializeCollection(SessionImpl.java:3307)

etc.

I'd attach the full stacktrace if I could; I'll be happy to email it to anyone who could help fixing this.
