Hi

I'm using the latest VisualVM 1.4.1 release on OpenJDK 1.8.0_131. When I try to run the Memory Profiling tool I get on the console of the Java process:

Profiler Agent: JNI OnLoad Initializing...
Profiler Agent: JNI OnLoad Initialized successfully
Profiler Agent: Waiting for connection on port 5140 (Protocol version: 18)
Profiler Agent: Established connection with the tool
Profiler Agent Error: Exception when trying to send response or command to client:

Any ideas?
