Hi,
in my SWT Application I am using iText to generate PDF documents. iText is
using AWT to get things done. Now, when launching my application from
within Eclipse on Mac, everything works fine until it comes to generation
of PDF. Then, an Exception is thrown that AWT is not working properly in
the current configuration. I've put -XStartOnFirstThread as JVM Argument
which seems to be the cause why AWT is not working.
I've never used the swt_awt bridge, but does it maybe have to do something
about it? Looking at the API it seems to only allow to use a JFrame or
Shell using AWT, but not other libs using AWT (like iText is using
java.awt.Color).
Thanks for help,
Ben

In general, you cannot mix AWT and SWT on MacOS X.
See https://bugs.eclipse.org/bugs/show_bug.cgi?id=67384 for details
However, if you use AWT non-interactively, it might be possible to run AWT
from an SWT application in "headless" mode. You'll need to set the
corresponding property before AWT gets initialized (and its event loop
starts).
