I'm currently getting a ORA-00936: missing expression error. It looks like the excludedProcessList is coming out blank... only () is show in the sql.

I added the following two lines to the application properties to get the following debugging info on the sql:
logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type.descriptor.sql.BasicBinder=TRACE
