Regression-CTE test CTE_REGTEST/Generic/4810806/NullPolyTest.java hangs intermittently because of
race conditions. The problem was described in 4943344 (which is 'fixed').

The test is used for testing starting from Tiger-b29.
It seems that the test is based on the non-fixed version of java/awt/Graphics/NullPolyTest/NullPolyTest.java.






Below is an excerpt from 4943344:

Regression test java/awt/Graphics/NullPolyTest/NullPolyTest.java fails intermittently
with JDK1.5.0, JDK1.4.2.

The problem is that waitLock.notify() in NullPolyTest.java at line 55 may be called before
the main thread enters waitLock.wait() at line 66, causing the test to hang.

Another minor possible problem is that waitLock.notify() is called only if the test passes.

After I had modified the test as follows:

14d13
< static boolean done=false;
54a54,56
  > synchronized (waitLock) {
  > waitLock.notify();
  > }
56,61d57
<
< synchronized (waitLock) {
< done=true;
< waitLock.notify();
< }
<
70c66
< while (!done) waitLock.wait(100);
---
  > waitLock.wait();


the test passed 10 times of 10.
