Seems that in new version of JDK, EnumSet<E> and <capture of ? extends
E> (E was previously stated as <E extends Enum<E>>) are not considered
compatible.
After changing
EnumSet<E> set = (EnumSet<E>)collection;
into
EnumSet set = (EnumSet)collection;
, compilation using ant in command line succeeds.
Would any one give a clue, why the are considered incompatible in this
version of JDK?
Eclipse uses its own JDK compiler, which may differ from this 1.5.0_08
version compiler.
Which IS differ :)
I mean Eclipse uses its own JDT incremental Java compiler (not JDK :-)
), which may differ from 1.5.0_08 version JDK compiler.
I guess this is the reason why compilation only fails in command line on
your machine.
