===============
I just built a small application and ran it against the latest build I could find (b80) of Merlin. The application Printtest.zip is attached to bug report.

Although the code works (except for the problem with the print orientation I mentioned) with 1.3, it crashes when I try to run it with 1.4. It dies when I attempt to print (I have included the dump below). Again, this same code does not crash when run against 1.3.

To simulate the problem:

Untar and uncompress the attachment. Set the path to JDK 1.4 Beta 2 distribution and then go into Projects directory and execute "java printtester/PrintTestApp1". Select the "Print Aw"t button under File menu. And select the Landscape option from the Page layout and "print to a file" option. One will see the above stacktrace immediately.

Verified with jdk build 1.4.0-rc-b89 on solaris 2.8, no exception occured when print to a file in landscape mode.
