Description Olivier Thomann

The following code should report an error:

public enum X {
	A
	;
	
	public abstract void foo();
}

Comment 1 Olivier Thomann

We report an error, but not the right error.
We report:

----------
1. ERROR in C:\tests_sources\X.java (at line 5)
	public abstract void foo();
	                     ^^^^^
The abstract method foo in type X can only be defined by an abstract class
----------
1 problem (1 error)

Javac reports:
X.java:1: X is not abstract and does not override abstract method foo() in X
public enum X {
       ^
1 error

Comment 2 Philipe Mulet

Indeed, the following should be accepted:
public enum X {
	A () { public void foo() {} }
	;
	
	public abstract void foo();
}

Support added. Also tagged enum classfile as abstract when defining abstract
methods (implicit).

Added regression tests: EnumTest#test052-055.
Fixed
