Description

YourKit performance analyzer showed that the call of InjectionResolver.implResolveByType() could be pretty expensive. The method uses caching except the case when no component is found. This case is skipped at the end of the metod as is visible at:

In our case we have huge JSF page with a lot of JSF Converters classes, that form injectionPointType input argument of the method. It is not clear why JSF converters are not found...
