Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server Liberty * **************************************************************** * PROBLEM DESCRIPTION: ClassCastException can occur during * * JNDI lookups * **************************************************************** * RECOMMENDATION: * **************************************************************** During a JNDI lookup it is possible for a ClassCastException. This only happens if (as a result of the lookup) a call to NamingManager.getObjectInstance is called and provided a lookup result that is not a javax.naming.Reference. This may happen when using JCA resource adapters, or doing a remote JNDI lookup. Exception = java.lang.ClassCastException Source = com.ibm.ws.jndi.internal.JNDIURLEntry probeid = ... Stack Dump = java.lang.ClassCastException: org.abc.sampleClass cannot be cast to javax.naming.Reference at com.ibm.ws.jndi.internal.JNDIURLEntry.getObjectInstance(JNDIURLE ntry.jav a:154) at org.apache.aries.jndi.ObjectFactoryHelper.getObjectInstanceUsing ObjectFa ctories(ObjectFactoryHelper.java:193) at org.apache.aries.jndi.ObjectFactoryHelper.getObjectInstance(Obje ctFactor yHelper.java:98) at org.apache.aries.jndi.OSGiObjectFactoryBuilder.getObjectInstance (OSGiObj ectFactoryBuilder.java:62) at javax.naming.spi.NamingManager.getObjectInstance(NamingManager.j ava:300)
Problem conclusion
The com.ibm.ws.jndi.internal.JNDIURLEntry was updated to do a type check so it ignores lookups where the object passed into getObjectInstance is not a Reference The fix for this APAR is currently targeted for inclusion in fix pack 16.0.0.2.
