"Testing 4.1.0.CR2 with a Hibernate app. We aren't seeing problems in the app but some ERRORs are logged that probably should not be.

In org.hibernate.cache.infinispan.util.CacheAdapterImpl is a method putAllowingTimeout - the intention is clearly that a TimeoutException is expected here and not to be considered a problem. So presumably nothing should be logged (or maybe something at the TRACE level).

However the InvocationContextInterceptor (see line 79) logs an error and rethrows the exception. Log and rethrow usually leads to double-logging anyway so this might not be the greatest practice. Not all callers consider this TimeoutException to be an error.

Here's a sample of the stack traces we get in the logs:
