Damn, I was expecting the fonts to show in alphabetical order (and it would have been the next one in your c:\windows\fonts directory that was the problem). But no, yours are listing in some other order. Does the order we're seeing make sense if you sort your fonts directory by the modified column? If so, remove the next one (after arial.ttf).

The other suggestion I've seen on the java sites is:

"I had this problem intermittently on Windows 2000 with Jdks 1.4 through 1.4.2.01. The problem did not occur with
1.3.1.01. I eventually traced the problem to a damaged/corrupt font in c:\WINNT\Fonts. I copied all the fonts in that directory to a temporary location, then deleted all the fonts in c:\WINNT\Fonts. I then copied all the fonts from the temporary location back into c:\WINNT\Fonts. This reinstalls the fonts and detects any corrupt/damaged fonts. I have not seen this error since reinstalling the fonts."

Obviously this would be c:\windows\fonts in your case.
