Description

I am attempting to use the validator with a large schema (OASIS UBL). When a request comes through, no response is generated, and the machine's CPU gets locked at 100% (previously with the default Java VM settings, a stack overflow error would occur, so I added -Xss 5m).

In order to replicate, I've created the attached tar file. Unzip/untar it under: ${SYNAPSE1.2_HOME}/repository/conf. Then, copy the file opensoa/synapse_sample_opensoa1.xml to ../sample and start synapse using ./synapse.sh -sample opensoa1. Submit any SOAP request to regenerate the error.

If you have any questions, write me at [e-mail].
