[Bug libgcj/24321] New: instanceof erroneously causes class initialization

[tromey at gcc dot gnu dot org]

Consider this program:

public class iof {
  static class Z {
    static {
      System.out.println("init");
    }
  }

  public static Object x () { return new Object(); }

  public static void main(String[] args)
  {
    System.out.println(x() instanceof Z);
  }
}


With gcj this prints "init".
With the JDK it does not.

Hmm, when compiled to native it works but not when using gij.

Note -noverify does not help with this case unlike PR 17021.

Fix checked in to trunk.
This may be a good 4.1.1 candidate.
