Undeterministic livelocks on JOSM startup

[wiktorn]

From time to time (looks like more less - since [8526]) I observe livelocks during startup before splash screen is shown. Thread dump analysis shows following threads:

I've observed this also on computer with fresh JOSM installation so I don't suspect any of the preferences. It occurs from time to time, I haven't found a reliable way to reproduce it.

Just happened it again on: version 1.8.0_45, vendor Oracle Corporation.

Duplicate of #11591?

After an evening with hacking on JOSM, on around 50-100 runs it occurred around 3-4 times. It might be due to the fact, that I moved to Java 1.8, that it's not so frequent, as I noticed earlier. Or maybe it's connected to network speed.

I think it's the same problem as #11591. We didn't have such problems before implementing the new splash screen.

Closed as duplicate of #11591.
