Ricky commented on WW-5506:
---------------------------
I can confirm, multipart loading has been revised starting with *Tomcat 11.0.8*
This is the relevant change in Tomcat source code, in the _else_ statement:
Before:
{code:java}
if (context.getAllowCasualMultipartParsing()) {
mce = new MultipartConfigElement(null, connector.getMaxPostSize(),
connector.getMaxPostSize(),
connector.getMaxPostSize());
} else {
partsParseException = new
IllegalStateException(sm.getString("coyoteRequest.noMultipartConfig"));
return;
}{code}
After:
{code:java}
if (context.getAllowCasualMultipartParsing()) {
mce = new MultipartConfigElement(null, connector.getMaxPostSize(),
connector.getMaxPostSize(),
connector.getMaxPostSize());
} else {
if (explicit) {
partsParseException = new
IllegalStateException(sm.getString("coyoteRequest.noMultipartConfig"));
} else {
parts = Collections.emptyList();
}
return;
}{code}
When a "multipart/form-data" content is sent, the new _explicit_ flag passed to
the function is set to {_}false{_}, so an exception is no longer thrown,
instead an empty parts collection is returned as it was in Tomcat 10.
So, {*}use Tomcat version >= 11.0.8 to get upload working{*}.

> Project: Struts 2
> Issue Type: Bug
> Components: Dispatch Filter
> Affects Versions: 7.0.0
> Environment: Tomcat 11.0.2
> WebApp based on Struts 7.0.0
> Reporter: Ricky
> Assignee: Lukasz Lenart
> Priority: Major
> Fix For: 7.1.0

> The method
> Dispatcher.{color:#000000}{color:#000000}createContextMap{color}{color}
> doesn't support Tomcat 11 new behaviour.
> Until Tomcat 10 the method Request.getParameterMap returned empty parts when
> multipart/form-data was posted. Now it throws an IllegalStateException.
> The exception rises al line:
> {color:#000000}{color:#000000}HttpParameters
> {color}{color:#6a3e3e}params{color}{color:#000000} =
> HttpParameters.{color}{color:#000000}create{color}{color:#000000}({color}{color:#6a3e3e}request{color}{color:#000000}.getParameterMap()).build();{color}{color}
