Something that sounds like a similar issue: Under OpenJDK, when trying to compile https://github.com/sk89q/worldguard (commit 49bdccf020 currently), I get
[INFO] Compilation failure /home/chris/Coding/bukkit/worldguard/src/main/java/com/sk89q/worldguard/protection/ApplicableRegionSet.java:[277,26] put(com.sk89q.worldguard.protection.regions.ProtectedRegion,V) in java.util.Map<com.sk89q.worldguard.protection.regions.ProtectedRegion,V> cannot be applied to (com.sk89q.worldguard.protection.regions.ProtectedRegion,java.lang.Object) but with the Sun JDK this error doesn't happen. -- You received this bug notification because you are a member of OpenJDK, which is subscribed to openjdk-6 in Ubuntu. https://bugs.launchpad.net/bugs/716959 Title: Incorrect generation/handling of generics compared to Sun javac? Status in “openjdk-6” package in Ubuntu: New Bug description: I'm currently packaging Jenkins (https://github.com/jenkinsci/jenkins/tree/jenkins-1_396 for a tarball) for Ubuntu and I've come across the following issue when compiling jenkins-core: /home/jamespage/src/hudson/github/build- area/jenkins-1.396/core/src/main/java/hudson/model/Build.java:[80,16] types hudson.model.AbstractBuild<P,B> and hudson.model.AbstractBuild<P,B> are incompatible; both define getParent(), but with unrelated return types /home/jamespage/src/hudson/github/build- area/jenkins-1.396/core/src/main/java/hudson/model/FreeStyleBuild.java:[35,7] types hudson.model.Build<hudson.model.FreeStyleProject,hudson.model.FreeStyleBuild> and hudson.model.Build<hudson.model.FreeStyleProject,hudson.model.FreeStyleBuild> are incompatible; both define getParent(), but with unrelated return types This is on natty (OpenJDK version below). java version "1.6.0_21" OpenJDK Runtime Environment (IcedTea6 1.10pre) (6b21~pre1-0ubuntu2) OpenJDK 64-Bit Server VM (build 19.0-b09, mixed mode) Compiling with the Sun JDK from the partner repository works successfully. I also get a similar issue on Maverick: /home/jamespage/src/hudson/github/normal/jenkinsci-jenkins- 653b030/core/src/main/java/hudson/model/Build.java:[80,16] types hudson.model.AbstractBuild<P,B> and hudson.model.AbstractBuild<P,B> are incompatible; both define getParent(), but with unrelated return types /home/jamespage/src/hudson/github/normal/jenkinsci-jenkins- 653b030/core/src/main/java/hudson/matrix/MatrixBuild.java:[60,7] types hudson.model.AbstractBuild<hudson.matrix.MatrixProject,hudson.matrix.MatrixBuild> and hudson.model.AbstractBuild<hudson.matrix.MatrixProject,hudson.matrix.MatrixBuild> are incompatible; both define getParent(), but with unrelated return types /home/jamespage/src/hudson/github/normal/jenkinsci-jenkins- 653b030/core/src/main/java/hudson/model/FreeStyleBuild.java:[35,7] types hudson.model.Build<hudson.model.FreeStyleProject,hudson.model.FreeStyleBuild> and hudson.model.Build<hudson.model.FreeStyleProject,hudson.model.FreeStyleBuild> are incompatible; both define getParent(), but with unrelated return types This feels like a difference between the way the Sun JDK and OpenJDK handle generics. _______________________________________________ Mailing list: https://launchpad.net/~openjdk Post to : [email protected] Unsubscribe : https://launchpad.net/~openjdk More help : https://help.launchpad.net/ListHelp
