Testsuite name: Regression
JDK/JRE tested: JDK8b111(32bit)
OS/architecture: oel6.4-redhat-x86
Reproducible: Always
Reproducible on machine: oel6.4-redhat-x86
Test run log location:
http://jsqalab.us.oracle.com/results/Evergreen/8/b111/regression/oel6.4-redhat-x86/results-awt-part5/workDir/java/awt/datatransfer/HTMLDataFlavors/ManualHTMLDataFlavorTest.jtr

Steps to reproduce:
1.Download regression workspace from http://jre.sfbay.sun.com/java/re/jdk/8/promoted/ea/b111/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-i586/jdk-7u25-linux-i586.tar.gz) to /regression/jdk1.7.0_25
3. Install test bundle JDK8b111 (download from http://jre.sfbay.sun.com/java/re/jdk/8/promoted/ea/b111/bundles/linux-i586/jdk-8-ea-linux-i586.tar.gz) to /regression/jdk1.8.0_111
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/jdk1.8.0_111 -r:/regression/results/reportDir -w:/regression/results/workDir /regression/test/java/awt/datatransfer/HTMLDataFlavors/ManualHTMLDataFlavorTest.html
 
Case Instruction:
1) The test contains a drop-aware panel with a red background
2) Open some page in a browser, select some text Drag and drop it on the red panel
    IMPORTANT NOTE: the page should be stored locally.otherwise for instance iexplore can
     prohibit drag and drop from the browser to other applications because of the protected mode
     restrictions.
3) Check the data in the output area of this dialog
4) The output should not contain information that any of flavors is not present in the system
    clipboard.
5) The output should contain data in three different formats provided by the system clipboard
    - Data after the "ALL:" marker should include the data from the the "SELECTION:" marker
    - Data after the "FRAGMENT" marker should include the data from the "SELECTION:" marker
      and may be some closing tags could be added to the mark-up
    - Data after the "SELECTION:" marker should correspond to the data selected in the browser
6) If the above requirements are met, the test is passed

Actual behavior:
Drag some text from the browser and drop it to the red panel ,the test failed automatically and thrown java.lang.NullPointerException.

Exceptions:
java.lang.NullPointerException
