System: Linux escher 2.4.9-21 #1 Thu Jan 17 14:16:30 EST 2002 i686 unknown
Architecture: i686

	
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ./configure --enable-threads=posix --prefix=/home/tstock/local --disable-shared --enable-languages=c++,java
>Description:
If you have a constructor in your Java class the finit$ is not inserted after the super call.  If you omit the constructor all is fine.
>How-To-Repeat:
public class Test
  {
  Object o = new Object();

  Test ( )
    {
      if ( o == null )
        {
          System.err.println("Test failed\n");
        }
    }

  static public void main ( String argv[] )
    {
      new Test();
    }
  }
>Fix:
It's not clear that build_super_invocation is required to force the CAN_COMPLETE_NORMAL flag, however without it I am not sure what might happen in the patch_invoke function.
