ArrayIndexOutOfBound exception under heavy load

[Argyn Kuketayev <Ar...@plateau.com>]

When I load test my document generation under Cocoon it throws me this:

java.lang.RuntimeException: java.lang.ArrayIndexOutOfBoundsException
        at
org.apache.xalan.transformer.TransformerImpl.run(TransformerImpl.java:3231)
        at java.lang.Thread.run(Thread.java:484)

This happens when I have ~80 user trying to generate the same document, it's
XSP+ESQL(Oracle) ->XSLT (to FO)-> XSLT (to HTML).

I increased all pool sizes to 200 for transformers.

Xalan (IMHO) has nasty error logging. This could be re-thrown exception,
and you original stacktrace might be lost.

See/hack TransformerImpl.java:3231.
