> Java Level Deadlocks
> Description
> This situation occurs if user or Ignite comes to a Java-level deadlock due to a bug in code - reverse order synchronized(mux1) {synchronized (mux2) {}} sections, reverse order reentrant locks, etc.
> Detection and Solution
> This most likely cannot be resolved automatically and will require JVM restart.
> We can implement periodical threaddumps analysis and detect the deadlock.
> Report
> Deadlock should be reported to the logs.
> Web Console should fire an alert on java deadlock detection and display a warning on UI.
