Issue:
When you try to login to the Workstation, you were getting the below error.

java.lang.RuntimeException: java.lang.NoSuchMethodError: javax.persistence.EntityManager.createQuery(Ljava/lang/String;Ljava/lang/Class;)Ljavax/persistence/TypedQuery;
at com.itko.lisa.gui.TestAdmin.setTestRegistry(TestAdmin.java:296)
at com.itko.lisa.gui.TestRegistryPanel.saveNewTestRegistry(TestRegistryPanel.java:127)

 
Environment:
All supported DevTest versions 
Cause:

Possible causes:

1) Incorrectly placing files in lib that should really be in hotDeploy.  Even so, if hotDeploy and lib contain definitions for the same classes, there could be issues.

2) Mismatch between workstation and Registry version.

Resolution:
Reinstalled 10.3, as some files were corrupted
