1997269 - Enable the SAPJVM tracing

Some of the JVM system properties have been changed and they cause different issues:

• Example 1:
  The deployment is failing with error: java.lang.ClassNotFoundException: com.sun.enterprise.iiop.POAEJBORB
  The reason for above error is because the system property "org.omg.CORBA.ORBClass" with default value "com.sap.engine.system.ORBProxy" was unexpectedly overwritten to "com.sun.enterprise.iiop.POAEJBORB" by a specific application or lib/service.
• Example 2:
  The XML parse will lead to excetion: NotSerializableException: com.sap.engine.lib.xml.parser.XMLParser
  The reason of the above error is because the system property "-Dorg.xml.sax.driver" with default value "com.sap.engine.lib.xml.parser.SAXParser" was unexpectedly overwritten to "com.sap.engine.lib.xml.parser.XMLParser" by a specific application or lib/service.
• Example 3:
  The "user.timezone" JVM parameter does not reflect the OS settings.

You want to identify the component which changes the JVM system properties by calling either System.setProperty(String key, String value) or System.setProperties(Properties prop).

Note: To enable on the go SAP JVM tracing that does not require a server restart, check SAP KBA ##2864787 - How to enable SAP JVM trace on the fly.
