There's a bug in 1.2 release. Reproduced on cache running in replicated mode
when IsolationLevel=NONE
cache.put() causes exception:
| Caused by: java.lang.RuntimeException: getLockStrategy: LockStrategy
selection not recognized. selection: NONE
| at
org.jboss.cache.lock.LockStrategyFactory.getLockStrategy(LockStrategyFactory.java:51)
| at org.jboss.cache.lock.IdentityLock.<init>(IdentityLock.java:75)

To fix it replace in LockStrategyFactory
|
| public static LockStrategy getLockStrategy(IsolationLevel lockingLevel)
| {
| //if(log_.isTraceEnabled()) {
| // log_.trace("LockStrategy is: " + lockingLevel);
| //}
| if (lockingLevel == null || lockingLevel_ == IsolationLevel.NONE)
| return new LockStrategyNone();
| if (lockingLevel == IsolationLevel.REPEATABLE_READ)
| return new LockStrategyRepeatableRead();
| if (lockingLevel == IsolationLevel.SERIALIZABLE)
| return new LockStrategySerializable();
| if (lockingLevel == IsolationLevel.READ_COMMITTED)
| return new LockStrategyReadCommitted();
| if (lockingLevel == IsolationLevel.READ_UNCOMMITTED)
| return new LockStrategyReadUncommitted();
| throw new RuntimeException("getLockStrategy: LockStrategy selection
not recognized." +
| " selection: " + lockingLevel);
| }
|
|
lockingLevel_ == IsolationLevel.NONE with lockingLevel == IsolationLevel.NONE
