[C2] sitemap_xmap.java bug?
Further on my quest to find why processing is taking longer than
anticipated (but processing time is not being noticed by the Profiler), I
notice the following lines appearing regularly in my compiled sitemap:
> if (true)
> return true;
>
>
> listOfMaps.remove (listOfMaps.size() - 1);
Clearly the listOfMaps.remove line is never going to be called. Is this
intentional?
This may or may not be related to my core problem which appears to amount
to the fact that some page requests are causing 16 new JaxpParser
components (TraxTransformers) to be generated in two lots of 8. This is
*not* under load - ie. one request at a time!
It appears as though the TraxTransformers are not being reused. However,
this doesn't happen all the time, it only appears to happen when the trax
transformation is part of a cocoon match which is being referenced within
another match in the sitemap using "cocoon:/"
Here's an example stack dump at the time:

Responses from folk who know this thing much better than I would be much
appreciated, I've been at this one for three days now and my previous
posts don't seem to have generated much interest! :-(

It came out of generation. If you find a solution you're very welcome to
patch it.

Vadim,
I've been keeping a close watch on CVS updates and the latest versions of
everything still reproduces the fault, but I'll take a look at your fix
and see if it inspires me!
Thanks,
Stuart.

I think yes. It might have the deal with some cases like this:
<map:match pattern="*">
<!-- listOfMaps.add -->
<map:match pattern="a">
...
</map:match>
<!-- listOfMaps.remove -->
</map:match>
<map:match pattern="b">
...
</map:match>
Request "b" would be processed by second match, and here it is nesessary to do .remove().

This might be the problem. Recently I patched SitemapSource which was not releasing
pipelines if cocoon: url processing fails. Try update your CVS.
