Steps to reproduce:
1.Download regression workspace from http://jre.sfbay.sun.com/java/re/jdk/8/promoted/ea/b112/ws/jdk/test/ to /regression
2.Install stable bundle JDK7u25b15 (download from http://jre.us.oracle.com/java/re/jdk/7u25/promoted/fcs/b15/bundles/linux-x64/jdk-7u25-linux-x64.tar.gz) to /regression/jdk1.7.0_25
3. Install test bundle openJDK8b112 (download from http://jre.us.oracle.com/java/re/jdk/8/promoted/ea/b112/openjdk/bundles/linux-amd64/jdk_ri-8-b112-linux-amd64-16_oct_2013.zip ) to /regression/java-se-8-ri
4.Download and unzip Jtreg from http://jre.us.oracle.com/java/re/jtreg/4.1/promoted/fcs/b02/bundles/jtreg_bin-4.1.zip locate at /regression
5.Create the script regression.sh as follows and run it
export JT_JAVA=/regression/jdk1.7.0_25 /regression/jtreg/linux/bin/jtreg -v -m -ignore:quiet -jdk:/regression/java-se-8-ri -r:/regression/results/reportDir -w:/regression/results/workDir /regression/test/java/awt/Modal/WsDisabledStyle/OverBlocker/OverBlocker.java

Case Instruction:
The test will be run 4 times, to start next test just close all windows of previous; the instructions are the same for all tests:
1) there is a frame with 'show modal' button,
2) press the button to show a dialog,
3) activate any non-Java application, move the app over the dialog,
4) click on the frame by mouse,
5) make sure that the dialog comes up from the application and now the dialog overlaps the app as well as the frame, if it's true, then the test passed, otherwise, it failed. Press 'pass' button only after all of the 4 tests are completed, the number of the currently executed test is displayed on the output window.

Actual behavior:
For the third and the forth tests: The dialog doesn't come up from the application after clicking on the frame by mouse refer to bug.png
