Cool, thanks for giving it a whirl.

If I remember correctly, the Text class was just a proposal in beta7 - it
existed but was not actually used anywhere. Therefore we didn't worry about
deprecating anything. Were you actually using it for something useful.

Searching for that error message in Google, I found these two interesting
links:

This tells me that some compilers (such as the JDK 1.1 javac) generated the
wrong code, but JRE 1.1 didn't complain. But JRE 1.2 does complain. So, in
general it sounds like you can't compile some code with javac 1.1 and run it
on JRE 1.2 or later. The solution would probably be to compile using the
fixed JDK 1.2 (or later) compiler, using the "-target 1.1" option, right?
