#27854

Obviously the exception is thrown in the standard JDK classes and the “problem” method (sun.net.www.protocol.file.Handler.openConnection (Handler.java:55)) has anything to do with URL connections.

A good strategy in the case would be to switch PD4Ml debug on (pd4ml.enableDebugInfo()) and to inspect STDOUT (or server’s log) for the last URL it tried to connect.
