A DESCRIPTION OF THE PROBLEM :
It seems this is a duplicate of Bug  JDK-7191086.

The problem only occurs on the Linux Platform. Windows 7 is working.

Pasting image which is ~ 1MB of size will cause a execption to occur!

See output here from testcase created (attached below):

Getting data from Clipboard
Fetching image
Error from Clipboard!!!!!!!!
java.io.IOException: Owner failed to convert data
	at sun.awt.X11.XSelection.validateDataGetter(XSelection.java:444)
	at sun.awt.X11.XSelection.getData(XSelection.java:378)done
	at sun.awt.X11.XClipboard.getClipboardData(XClipboard.java:120)
	at sun.awt.datatransfer.ClipboardTransferable.fetchOneFlavor(ClipboardTransferable.java:117)

	at PasteTest.paste(PasteTest.java:26)
	at PasteTest.main(PasteTest.java:51)



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.) Open with a browser e.g. Firefox a large picture (size > 1MB) and copy the graphic into the clipboard.
2.) Run test case several times. You should see it fail

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No expection to occur!
ACTUAL -
Exception occurs!

REPRODUCIBILITY :
This bug can be reproduced often.
