Tested with Merlin b56 on Solaris 8 SPARC and Solaris 7 SPARC.
Selecting "save" from Applet menu, appletviewer ends abnormally.
This problem is seen from merlin-beta b55 and reproducible with b56.
It occurs on both of 32-bit and 64-bit machine.
It occurs on both of ja locale and C locale.

To reproduce:

1. Launch appletviewer with any demo under $JAVAHOME/demo/applets/.
for example, plese use Clock demo.
With Server VM on 64-bit machine:
> appletviewer -d64 -server example1.html

With Server VM on 32-bit machine:
> appletviewer -server example1.html

With Client VM on both of 64-bit and 32-bit machine.
> appletviewer example1.html

2. Select "Save" from Applet menu.

Then, the problem occurs and error messages as below are displayed.
