Ross Clewley commented on PORTLETBRIDGE-234: -------------------------------------------- The signature of the remove method in BridgeRequestScopeRepository is public BridgeRequestScope remove(String key) Confusingly, BridgeRequestScope is not a class name in this context but a generics type parameter name (this is somewhat misleading and probably ought to be cleaned up): public class BridgeRequestScopeRepository<String, BridgeRequestScope extends ConcurrentMap<String, Object>> extends LinkedHashMap<String, BridgeRequestScope> Therefore BridgeRequestScope will be erased at runtime, leading to the conflict with the superclass method from HashMap which is declared as: public V remove(Object key) { }. > remove(String) in BridgeRequestScopeRepository and remove(Object) in HashMap > have the same erasure. > --------------------------------------------------------------------------------------------------- > > Key: PORTLETBRIDGE-234 > URL: https://issues.apache.org/jira/browse/PORTLETBRIDGE-234 > Project: MyFaces Portlet Bridge > Issue Type: Bug > Components: Impl > Affects Versions: 3.0.0 > Reporter: Ross Clewley > Assignee: Michael Freedman > > Compiling the portlet bridge impl project on trunk produces the following > compilation error. > [ERROR] Failed to execute goal > org.apache.maven.plugins:maven-compiler-plugin:2.3.1:compile > (default-compile) on project portlet-bridge-impl: Compilation failure > [ERROR] > /myfaces-trunk/impl/src/main/java/org/apache/myfaces/portlet/faces/bridge/scope/BridgeRequestScopeRepository.java:[55,28] > error: name clash: remove(String) in BridgeRequestScopeRepository and > remove(Object) in HashMap have the same erasure, yet neither overrides the > other -- This message was sent by Atlassian JIRA (v6.2#6252)
