Description

2.3.1

I am using a cached transformer, as well as a cached menu(xml) document for a
very common transformation (menu). The transform works well 99.9% of the time,
but occasionally fails. After failure, without restarting the VM, try again
and it works! There is not more than one xml, or transformer in cache (I am
simply using a private member field.

I am unable to recreate this error with any precision, but it does usually
happen after the VM has been running for more than 30 minutes.
