allle i might have a use case a bit like yours, look at my isolation unit test in the other thread http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4254357#.... If i use cache.getCache().getConfiguration().setNodeLockingScheme(NodeLockingScheme.PESSIMISTIC);, the test passes. If i use cache.getCache().getInvocationContext().getOptionOverrides().setForceWriteLock(true); instead, the test fails. If i use cache.getCache().getInvocationContext().getOptionOverrides().setForceWriteLock(true); | cache.getCache().getConfiguration().setWriteSkewCheck(true);, the test fails and JBC detects writeSkews. But what i want is not the read thread to fail, but to block until the write thread is over. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4256796#...
