MVN compilation issue

[Marcus Frex]

There are some errors while Maven compilation which are like;

Users/marcus/Development/jhears/jhears-persistence/src/main/java/org/jhears/data/BerkeleyMap.java:[149,36] type parameters of <E>E cannot be determined; no unique maximal instance exists for type variable E with upper bounds V,java.lang.Object

/Users/marcus/Development/jhears/jhears-persistence/src/main/java/org/jhears/data/BerkeleyMap.java:[176,43] type parameters of <E>E cannot be determined; no unique maximal instance exists for type variable E with upper bounds V,java.lang.Object

/Users/marcus/Development/jhears/jhears-persistence/src/main/java/org/jhears/data/BerkeleyMap.java:[396,34] type parameters of <E>E cannot be determined; no unique maximal instance exists for type variable E with upper bounds K,java.lang.Object

/Users/marcus/Development/jhears/jhears-persistence/src/main/java/org/jhears/data/BerkeleyMap.java:[403,39] type parameters of <E>E cannot be determined; no unique maximal instance exists for type variable E with upper bounds V,java.lang.Object

I fixed that by using casting operators. But that should be fixed in GeneralDAO, HibernateMap and BerkeleyMap Classes.

This is a bug in Sun javac:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6302954

Confirmed with:
java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b06)
Java HotSpot(TM) 64-Bit Server VM (build 17.0-b16, mixed mode)

Code compiles correctly with OpenJDK:
