> *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.
