APAR status
Closed as program error.
Error description
When attempting to use jars through the shared-classes directory, if they contain classes that are defined in the MQ local jars, the shared-classes jars will be ignored, and the MQ local version will be loaded. For example, bouncycastle jars are included in the MQ local jars, resulting in any bouncycastle jars included in shared-classes being ignored.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: All users of IBM Integration Bus v10.0.0.8 or above adding jars to the classpath using the shared-classes folder. Platforms affected: z/OS, MultiPlatform **************************************************************** PROBLEM DESCRIPTION: When adding a jar to the shared-classes directory for use in the Java compute node, if the classes also exist in the MQ prereq jars shipped with the product then the classes will be loaded from the MQ prereq jars, rather than the user jars. For example, bouncy castle jars are shipped as part of the local copy of MQ, so any bouncy castle jars in the shared-classes directory would be ignored. This may cause customer java code to behave in unexpected ways.
Problem conclusion
Classloading has been changed for MQ jars, removing the possible conflicts from the classpath of the java compute nodes. A new environment variable has been defined: MQSI_DISABLE_SHIPPED_MQ If this has been set, the shipped MQ jars will be removed from the class path, and the use of MQ dependant nodes in the product will be disabled. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v10.0 10.0.0.10 v9.0 9.0.0.9 The latest available maintenance can be obtained from: http://www-01.ibm.com/support/docview.wss?rs=849&uid=swg27006041 If the maintenance level is not yet available,information on its planned availability can be found on: http://www-1.ibm.com/support/docview.wss?rs=849&uid=swg27006308 ---------------------------------------------------------------
