Peter Ertl resolved WICKET-5647. -------------------------------- Resolution: Fixed > missing generic cast causes compile error on OS X / jdk 8 > --------------------------------------------------------- > > Key: WICKET-5647 > URL: https://issues.apache.org/jira/browse/WICKET-5647 > Project: Wicket > Issue Type: Bug > Components: wicket > Affects Versions: 6.16.0, 7.0.0-M2 > Environment: OS X 10.9.4 > JDK 1.8.0_11 > Reporter: Peter Ertl > Assignee: Peter Ertl > Fix For: 7.0.0-M3, 6.17.0 > > > when trying to compile wicket-7 from HEAD it fails under OS X / JDK 1.8.0_11. > Casting a NULL to generic type (T) solves the issues. This seems like some > odd case of failing type inference. > The problematic source line is: > return getEnumImpl(key, eClass, null); > The compiler error is: > Error:(792, 35) java: incompatible types: inference variable T has > incompatible upper bounds java.lang.Enum<T>,T > This will fix the issue: > return getEnumImpl(key, eClass, (T)null); > I found that there is a fix WICKET-5427 which does not work in most current > JDK 1.8.0_11 anymore. -- This message was sent by Atlassian JIRA (v6.2#6252)
