Description Michael Enke 2003-06-23 15:47:34 UTC 
If I have a %25 as part of the request (%25 is the percent sign), I get this
exception:

java.io.CharConversionException: EOF

Comment 1 Bill Faulk 2004-02-16 18:01:43 UTC 
I get the same error on Tomcat 4.1.29 whenever a parameter contains a percent 
sign. Specifically, request.getParameter generates 
the "java.io.CharConversionException: EOF" if the parameter value contains a 
percent sign. This can happen with both GET and POST form methods. I don't 
believe encoding the URL isn't an option even if it would work.
Comment 2 Bill Faulk 2004-02-16 18:03:49 UTC 
Additional information: I am running Windows 2000 Server. The same error was 
previously reported for URL forwards.

Comment 3 Mark Thomas 2004-06-19 12:24:19 UTC 
This bug report has been transferred to Tomcat 5 because TC4 and TC5 share the 
connectors and TC5 is now the focus of development effort
Comment 4 Mark Thomas 2004-06-19 15:43:11 UTC 
If you re-open this, please provide a test case as I can't reproduce it.
