Hi Jon, thanks for the quick reply.

The file currently resides in the Assay folder, is owned by the tomcat user and part of the tomcat group, and has permissions 777. The folder is also tomcat owned, and has permissions 755.

I'm not sure if this helps, but the curious thing is that none of this was an issue earlier in the week. The only thing that changed was the execution command in the script engine configuration (we added some sys arguments). We noticed this issue afterwards, but upon reverting, the error persisted.

Please let me know if you need anymore information, thanks again.

Simon
