Java 2 Platform SE v1.3 Specification reads about java.lang.Object.wait() method:

public final void wait()
                throws InterruptedException

      Causes current thread to wait until another thread invokes the notify() method
      or the notifyAll() method for this object. In other word's this method behaves
      exactly as if it simply performs the call wait(0).
---------------------------------------------------------------------------------

The following test shows incorrect behavior of Object.wait() method,
this method terminates immediately without notify() method invocation.

This test fails only in Java HotSpot(TM) Client VM (build 1.3.0beta-b01, mixed mode) for linux.
The following list of JCK1.3 tests fails by the same reason:
  1. api/java_lang/Object/desc.html#Wait
  2. api/java_lang/Object/desc.html#Notify
  3. api/java_lang/Object/desc.html#NotifyAll

--------------------------test.java------------------------------
public class test {

  public synchronized void getState() {

    System.out.println("Waiting is started");
    try {
        wait();
    } catch( InterruptedException e ) {
    }

    System.out.println("Waiting is finished");
  }

  public static void main( String[] argv ) {
    new test().getState();
  }
}
------------------------------------------------------------------

Please note that if you use wait(n) where n is greater than zero instead of wait()
the test won't fail on linux.

The test passes if only "Waiting is started" is printed
and then test is blocked in wait() method until user interrupts it with Ctrl+C

-----------------------------output--------------------------
Linux:

[kotl@linux-4 Object]$ java test
Waiting is started
Waiting is finished
[kotl@linux-4 Object]$

Solaris:

bash-2.00$ java test
Waiting is started
^C
bash-2.00$

The bug is reproducible under jdk1.3.0beta-bo4 in Xcomp mode
