Testsuite name: Regression
JDK/JRE tested: JDK7u55b08(64bit)
OS/architecture: win7-sp1-x64
Reproducible: Always
Reproducible on machine: win7-sp1-x64
Test run log location:http://jsqalab.us.oracle.com/results/Evergreen/7u55/b08/regression/win7-sp1-x64/results-awt-part5/workDir/java/awt/FileDialog/FileDialogReturnTest/FileDialogReturnTest.jtr

Steps to reproduce:
1.Download regression workspace from http://jre.sfbay.sun.com/java/re/jdk/7u55/promoted/fcs/b08/ws/jdk/test/to c:/regression
2. Install test bundle JDK7u55b08 (download from http://jre.us.oracle.com/java/re/jdk/7u55/promoted/fcs/b08/bundles/windows-amd64/jdk-7u55-windows-x64.exe ) to C:/Java/jdk1.7.0_55
3.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 C:/regression
4.Create the script regression.sh as follows and run it
export JT_JAVA=C:/Java/jdk1.7.0_55
C:/regression/jtreg/win32/bin/jtreg -v -m -ignore:quiet -jdk:C:/regression/jdk1.7.0_55 -r:C:/regression/results/reportDir -w:C:/regression/results/workDir C:/regression/test/java/awt/FileDialog/FileDialogReturnTest/FileDialogReturnTest.html

Instruction:
 1. The test shows the 'FileDialogReturnTest' applet which contains two text fields and one button,
 2. Input something into the 'File:' text field or just keep the field empty,
 3. Input something into the 'Dir:' text field or just keep the field empty,
 4. Press the 'Show' button and a file dialog will appear,
 5-1. Cancel the file dialog, e.g. by selecting the 'close' menu item,
 If the output window shows that 'file'/'dir' values is null then the test passes, otherwise the test fails,
 5-2. Select any file, e.g. by pressing the 'OK' button, If the output window shows that 'file'/'dir' values is not-null then the test passes, otherwise the test fails.

Actual behavior:
1) For 5-1 step: if input something into the 'File:' and 'Dir:', the dir output isn't empty in the output window after showing and canceling the file dialog refer to FileDialogReturnTest.jpg.
2) For 5-1 step: if keep the 'File:' and 'Dir:' field empty, it is pass.
