Regression-test java/beans/PropertyChangeSupport/4682386/TestMain.java test fails because of
race conditions:

bean.setFoo(!bean.isFoo()) in PropertyThread is executed before
bean.addPropertyChangeListener(new PropertyHandler()) in AddThread and
support occures to be null in setFoo.

After I had modified testThreading() as follows, the test passed.

      public void testThreading() {
          bean = new TestBean();

          Thread add = new AddThread();
          Thread remove = new RemoveThread();
          Thread prop = new PropertyThread();

          add.start();
          try{ Thread.sleep(100); }catch(Exception e){}
          prop.start();
          remove.start();
      }
