Java-level deadlock detected
This means that some threads are blocked waiting to enter a synchronization block or
waiting to reenter a synchronization block after an Object.wait() call, where each thread
owns one monitor while trying to obtain another monitor already held by another thread.
Deadlock:
onos-gui-msg-sender is waiting to lock org.onosproject.ui.impl.UiWebSocket@ca3950 which is held by Timer-2
Timer-2 is waiting to lock org.onosproject.ui.impl.TopologyViewMessageHandler@716974f1 which is held by onos-gui-msg-sender
