There are several failure with reason
"Cannot invoke "String.equals(Object)" because "<local1>" is null"
which really caused by reading the command from debugee via socket.
Like:
String command = pipe.readln();
if (!command.equals(AbstractDebuggeeTest.COMMAND_READY)) {
setSuccess(false);
log.complain("TEST BUG: unknown debuggee's command: " + command);
return false;
}
The command is null when socket fails with EOFException which usually means
that debugee has been crashed/exited or killed by timeout handler.
However, it is not clear from the error log. So
https://bugs.openjdk.org/browse/JDK-8310940 has different problems with the
same NPE symptom.
The fix update error handling to improve logging.
So output loos like:
