EJBTransactionManager.GetEJBTransactionContext Causes 100% CPU Usage in Oracle Application Server 10.1.3.5 (Doc ID 1443263.1)

Last updated on OCTOBER 15, 2020

Applies to:

Oracle Containers for J2EE - Version 10.1.3.5.0 and later
Information in this document applies to any platform.

Symptoms


On several occasions 100% CPU usage is observed as well as many ‘stuck’ threads.
Apparent infinite loop in HashMap.get() operation, within the EJBTransactionManager, is seen and believed to be caused by unthread safe use of HashMap class within the EJBTransactionManager class.
