[jira] [Updated] (OWB-1457) [perf] Reuse generics “visited” map in InjectionResolver#implResolveByType

     [ https://issues.apache.org/jira/browse/OWB-1457?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Thomas Andraschko updated OWB-1457:
-----------------------------------
    Description: 
During implResolveByType, GenericsUtil.satisfiesDependency was called with a new HashMap for every bean API type (and again inside findByParameterizedType / findByBeanType). That caused many short-lived maps on each cache miss or startup validation.

Allocate one HashMap<Type, Integer> per implResolveByType invocation, clear() before each satisfiesDependency call, and pass it through findByParameterizedType and findByBeanType. Semantics are unchanged
