Using gradle 1.0-rc-3 Encountered this in a unit test which fires up an embedded active MQ broker, looks like something do do with gradle consuming stdout is preventing the log4j call from the blocking thread from completing while log4j has a lock on the category that the blocked thread is trying to log to.
Able to work around by limiting log4j to FATAL during tests to basically silence it, but it doesn’t seem ideal that a log operation gets hung up.
