Hi

I am running Jenkins 1.552. I upgraded to the latest verstion of the Active 
Directory (1.34) and Parameterised Trigger plugin (1.24) and Static Analysis 
plugin (1.56).  Now many of our slaves do not launch:


Connecting to r102

ERROR: Unexpected error in launching a slave. This is probably a bug in Jenkins

I have tried rolling back the Active Directory and Parameterised Trigger 
plugins to their previous versions but the problem remains.

Any suggestions as to what is going wrong please?

Best regards

David
