EVALUATION
Yes, it's a regression of 7177040. The reason is that isFlushingPendingEvents in SunToolkit.flushPendingEvents() is reset after the first recursive call of flushPendingEvents(). Thus, if there are several pending events in PostEventQueue, recursion would be rejected only for the first event, allowing nested call of PostEventQueue.flush().

Looks like a regression of 7177040. I should build jdk7u8 without the fix to verify this.
