You should enter a bug report against Platform SWT.  Please specify what 
eclipse build you were using and what platform you were running on.

[platform-swt-dev] Usage Clipboard object multiple times in SWT






Hello together,

if I run the following code in several Thread, but not in parallel, I can
access the clipboard object only for one time, even if a get a new 
Instance
on every new call:

                 Clipboard cb = new Clipboard(Display.getCurrent());
                 String textData = "Hello World !";
                 TextTransfer textTransfer = TextTransfer.getInstance();
                 cb.setContents(new Object[]{textData}, new 
Transfer[]{textTransfer});
                 cb.dispose();

The error by calling on the second time looks like this:

org.eclipse.swt.SWTError: Cannot set data in clipboard

Any ideas and help on this error is appreciated.
