    Description

      This is interesting.

      It looks like jline is not silenced to ignore UI events it doesn't expects.

      If I minimize/maximize my Terminal, which corresponds to the linux package terminator-1.91-2.fc26.noarch

      I get this error spitted in the CLI console:

      Exception in thread "SIGWINCH handler" java.lang.UnsupportedOperationException
	at org.jline.terminal.impl.NativeSignalHandler.handle(NativeSignalHandler.java:24)
