[Bug java/19674] New: Empty declaration through semicolon (;) causes compile failure

[mark at gcc dot gnu dot org]

The following program doesn't compile:

public interface OutSideInterface
{
  public interface InsideInterface
  {
    void m(int p, int p2);
  };
}

Note the empty statement (semicolon) on line 6.
This is legal (jikes accepts it) but deprecated.

Compiling with -C gives:

OutSideInterface.java:6: error: '{' expected.
     };
      ^
OutSideInterface.java:7: error: Class or interface declaration expected.
   }
   ^
2 errors

Reported by Jerry Haltom.


With -Wextraneous-semicolon the compiler does see that this is just an declaration:

OutSideInterface.java:6: warning: An empty declaration is a deprecated feature
that should not be used.
