> *Issue* We are using TomEE1.7.4 and we are trying to upgrade to TomEE8.0.6.
> We are seeing WebappBeanManager calls getInjectionPointBean results in lot of
> UnsatisfiedResolutionException where in TomEE.1.7.4 there are no such
> exceptions.
> UnsatisfiedResolutionException is not an issue but leads to thread blocking
> issue due to an issue in openwebbeans.
> Our functionality works fine as the it finds the bean somewhere else but we
> get a performance issue due to repeated UnsatisfiedResolutionException thrown
> by openwebbeans code.
> *Observation:*
> [https://github.com/apache/tomee/blob/master/container/openejb-core/src/main/java/org/apache/openejb/cdi/WebappBeanManager.java]
> We observed WebappBeanManager code is making some redundant call to with
> parentBm.getInjectionResolver().getInjectionPointBean(injectionPoint)
> resulting some in UnsatisfiedResolutionException but application works fine
> but we get in to thread blocking issues due to this exception from
> openwebbeans.
> *Openwebbeans issue* (https://issues.apache.org/jira/browse/OWB-1388)* :
> It has a instance variable with making System.Property call which calls
> java.util.HashTable (synchronized get method) causing threads to block.
> _private_ _final String lineSeparator =
> System.getProperty("line.separator");_
>
> *Change requested:*
> Either fix the WebappBeanManager class so that UnsatisfiedResolutionException
> is avoided when everything works fine.
> *Or*
> Once *OWB-1388* is fixed please patch with TomEE 8.0.6. If exception can't be
> avoided then at at least threads will not be blocked causing a significant
> performance issue.
