Description Jeff Johnston 2006-11-03 21:26:49 UTC 
The Eclipse code uses regex to form a list of file names to perform operations such as rename or search upon.  The code to do this starts by creating a set of reusable matchers created with an empty string,  Then whenever it needs to do a regex match, it resets the string via the reset() method.  This does not work under classpath, but does work under the Sun JDK.

A simple testcase tested on i686 FC6 is attached.

Comment 2 Ito Kazumitsu 2006-11-06 01:29:23 UTC 
Resetting the instance variable this.inputCharIndexed = RE.makeCharIndexed(input, 0); has been missing in the metod reset(CharSequence input).  I will fix it ASAP.
