Coyote causes StackOverflowError when HTTP transmission interrupted

           Summary: Coyote causes StackOverflowError when HTTP transmission
                    interrupted
           Product: Tomcat 4
           Version: 4.0.4 Beta 2
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: Connector:Coyote
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: regml@btinternet.com


It is fairly easy to cause Coyote to enter a loop which ends up in a
StackOverflowError and renders it unusable.

With a fairly large web page as test content (say around 50kB), use a browser to
download it; then refresh repeatedly, before the whole page content has had a
chance to get to you.

Stack trace is as follows:

java.lang.StackOverflowError

 (and so on!)
