Environment

Identity Manager (standalone 14.x)

Cause

Mismatch in version of Java used by Symantec_migrate_tool.bat tool. 

Resolution

1. Locate the Java used by the JBoss EAP to be migrated (look in standalone.bat)
2. On the machine running Symantec_migrate_tool.bat tool, set %JAVA_HOME% to Java used by the JBoss EAP from step 1.
