The broken code that deadlocks is result of following commit (into JDK8 tree): 6737:d1668eca22bf - mchung Nov 27, 2012 6664509: Add logging context 6664528: Find log level matching its name or value given at construction time Reviewed-by: alanb, ahgross, jgish, hawtin It is not present in JDK7_u07 - it has been backported later.
