BWENGINE-100006 BWENGINE-100006

java.lang.Exception: BWENGINE-100048

        at com.tibco.pe.core.WorkflowBuilder.build(WorkflowBuilder.java:48)
        at com.tibco.pe.core.WorkflowLoader.setWorkflows(WorkflowLoader.java:113)

Cause: On some platform, especially on Linux system, the order in which the jar files are picked and appended in classpath are different, causing this issue.

Workaround:
-----------
- edit &ltTIBCO_HOME>/bw/5.6/bin/bwengine tra file and explicitly added the engine.jar in the beginning of classpath for 'tibco.env.CUSTOM_EXT_PREPEND_CP' property and redeploy the project. Or directly add it in deployed engine tra file.

example:
tibco.env.CUSTOM_EXT_PREPEND_CP=/tibco/bw/5.6/hotfix/lib/engine.jar:/tibco/bwhotfix/bw/5.6/hotfix/lib
