Last updated on APRIL 13, 2018

Applies to:

Oracle Weblogic Server - Version 9.2 to 10.3
Information in this document applies to any platform.

Symptoms

When making calls to EJB's from client code, we get a warning message saying "The EJB Lock Manager has received an unlock request from EJB:SystemTask with primary key".

javax.ejb.EJBException: [EJB:010108]The EJB Lock Manager has received an unlock request from EJB:sims.ejb.GridSetupLEB with primary key:CT.


However, this primary key can't be found in the Lock Manager. This indicates either an EJB container bug, or the 'equals' and 'hashCode' methods for the primary key class:com.sims.ejb.user.UserPK are implemented incorrectly.

Please check the 'equals' and 'hashCode' implementations.
