OneWay invocations to a webservice result in ERROR [STDERR] [Fatal Error] :-1:-1: Premature end of file.

When tried to invoke Oneway method on WS endpoint I got this exception. The invocation of Oneway method itself is correct (all statements in Oneway method are executed), but after this invocation there is a Premature end of file error in the client. (See following stacktrace).

This issue came as a part of SOA-1945. There were problems with our WISE SOAPClient, after these were solved Premature end of file appeared in the server console. It was tracked down that this issue originates in JBossWS (see linked issue for details)
