Another freeze

[matejdro]

I've managed to get Niddler to freeze Android Studio once again. Here is the thread dump:

Found one Java-level deadlock:
=============================
"AWT-EventQueue-0":
  waiting to lock monitor 0x00007f107c0f7c00 (object 0x0000000717e1f588, a java.util.ArrayList),
  which is held by "WebSocketConnectReadThread-1158"
"WebSocketConnectReadThread-1158":

  which is held by "AWT-EventQueue-0"
