I have checked activemq 5.7.0 in tags directory. Ad 1) The messagesLock in Queue class is used in much the same way (in iterate() and sendMessage() methods). The FilePendingCursor still waits for the available space in tryAddMessageLast() and the waiting seems to be implemented in the same way in the waitForSpace() method of the Usage class. Ad 2) The FilePendingCursor still uses synchronized methods - at least the tryAddMessageLast() for writers and next() for readers. Ad 3) The TempUsage.retrieveUsage() uses PListStore.size() and that is still implemented as: return journal.getDiskSize() + pageFile.getDiskSize(); I have not investigated further, but it will probably always return the same value as in 5.4.2. Therefore, all the three issues are likely present in the 5.7.0 too. I can spare some time to check whether 5.7.0 hangs too if you wish. I may also provide you an access to our private repository for cherrypicking the changes.
