Description
JCK: JCK-runtime-6b alt
J2SE: FAIL - JDK7b24, JDK6-Open-b01, JDK6-Open-b02
PASSES - JDK1.5.0u14, JDK1.6.0u3
Platform[s]: FAIL - Solaris-SPARC, WindowsXP, Linux
The following test:
api/java_awt/Container/index.html#isAncestorOf[Container2019]
takes unmeasurable amount of time to work - more than 6 hours and still gives no results.
The essence of the test that causes hanging is the following:
---------------------------------------------------------------
final int NUMBER_OF_CONTAINERS = 50;
Container[] containers = new Container[NUMBER_OF_CONTAINERS];
containers[0] = new Container();
for (int i = 1; i < containers.length; i++) {
containers[i] = new Container();
containers[i - 1].add( containers[i] );
}
---------------------------------------------------------------
Number of 50 is critical, with 30 containers this code works fine.
For JDKs 1.5.0u14/1.6.0u3 it's a matter of seconds to go through all 50 containers.
