The ++HBRWORKPATH++/res_xom directory contains empty jar file, JAVA_XOM_NAME.jar with size 0, without corresponding sha1 file (JAVA_XOM_NAME.jar.sha1)
Accepted answer
The short term solution to solve the problem is to delete the empty jar files and restart the server.
The long term solution, because such problem is likely to be the consequence of space availability issue of the ++HBRWORKPATH++ file system, is to create a dedicated file system for ++HBRWORKPATH++/res_xom and ++HBRWORKPATH++/res_data.
