That doesn't seem to be the problem. Regardless of variable names, the problem still occurs (we tried changing them around earlier as a last resort). The parameter is already corrupt after being received by the constructor, and before any assignment.
Also, the local instance variable is identified by "this." -----Original Message----- From: Phillip Morelock [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 29, 2002 11:02 AM To: Tomcat Users List Subject: Re: Memory Leak? You are using the same name for the parameter to the constructor and the instance variable for your inner class. fillup On 5/29/02 10:55 AM, "Mark Shurgot" <[EMAIL PROTECTED]> wrote: > I am having the strangest problem with Tomcat and inner classes.
