I can't be more specific because this ONLY occurs when tomcat is
started without a debugger. If I attach the debugger, it seem that the
RequestWrapper initialises correctly and the parameter is found.

Did you check tomcat's source code for the version you are running? I'm
curious what is at this line
java.lang.NullPointerException at

Without knowing code at that line, I can only guess that there is
something wrong with incoming request and tomcat fails to parse it...
I hadn't so I did a little bit of digging through the Tomcat 6.0.14
source over the evening. It gets more interesting as the code at
org.apache.catalina.connector.Request.parseParameters(Request.java:2426)
is shown below.
if (!getMethod().equalsIgnoreCase("POST"))
return;
for completeness...
/**
* Return the HTTP request method used in this Request.
*/
public String getMethod() {
return coyoteRequest.method().toString();
}
... Coyote.Request
public MessageBytes method() {
return methodMB; <-- This value is initialised in the class
declaration.
}
public MessageBytes requestURI() {
return uriMB;<-- This value is initialised in the class
declaration.
}
public String toString() {
return "R( " + requestURI().toString() + ")";
}
Unless I'm being a bit thick, it doesn't explain why the getMethod()
appears to sometimes return null.
The Java version being used is java version "1.6.0_05" server
One for the tomcat mailing list I think.
