Unhappy Apache: rewrite engine and regular expressions

Howdy folks! I have this little problem. I have a php script called highlight.php that takes a .java file and prints it out with the Text Highlighter package from PEAR. Apache comes in when I write a RewriteRule in .htaccess that will take anything with .javas and send it to my php script. Here's the RewriteRule:
RewriteEngine on
RewriteRule ^(.*?)\.(java|JAVA)s|S$ highlight.php?file=$1.$2
Now for the problem. Apparently Joomla! uses some file called includes/js/joomla.javascript.js and my RewriteRule interferes with this file and makes it

This is the error I'm getting:
[24-Mar-2009 14:57:47] PHP Warning:  file_get_contents(includes/js/ [<a href='function.file-get-contents'>
function.file-get-contents</a>]: failed to open stream: No such file or directory in ~/public_html/highlight.php on line 15
I've been online for hours studying different sites about regular expressions and scratching my head and getting no where's. I thought that the $ at the end of the regexp would only match if it was indeed the end of the string. Any suggestions would be much appreciated.

How about:
RewriteEngine on
RewriteRule (.+\.)(javas?)$ highlight.php\?file=$1$2 [NC,L]

works for me

(.+\.) = Match anything before the .
(javas?)$ = match Java, JAVA, javas, JaVaS or any combo like that
NC,L = Case insensitive, Last rule (if matched, will stop here)

Seems to work so far. Joomla! isn't sending PHP errors anyways. I revised it just a bit so my highlight.php will open it:
RewriteRule (.+\.)(java?)s$ highlight.php\?file=$1$2 [NC,L]
Thanks a lot for the solution. What I had done to get around it in the first place was I stuck all the files I wanted to parse with Text_Highlighter in a separate folder and and stuck the .htaccess with the mod_rewrite into that folder also. That way it didn't interfere with any other files. It was probably more secure that way also. It irked me so much that it was matching that includes/js/joomla.javascript.js, but your solution, Grizly, seems to have fixed that.
