form with enctype="multipart/form-data" does not support large input data (16425 bytes)

[dyegocarmo]

Beginning with wildfly 30.0.0 parameter with more than 16425 Bytes input data are ignored if form has enctype "multipart/form-data"

BackingBean:
package bug;

import java.io.Serializable;

import jakarta.enterprise.context.RequestScoped;

import jakarta.inject.Named;

@nAmed

@RequestScoped

public class BackingBean implements Serializable{

private String content;

private String test = "1";

public String getContent() {

return content;

}

public void setContent(String content) {

this.content = content;

}

public String getTest() {

return test;

}

public void setTest(String test) {

this.test = test;

}

public void action() {

test +="AAAAAAAAAAAAAAAAAAAAAAA\n";

System.out.println("Size of test:"+test.length());

}

{color:#000000}}

A complete example working is inside https://issues.redhat.com/browse/WFLY-18821

[dyegocarmo]

Version Mojarra inside Wildfly 30 is 4.0.4

[dyegocarmo]

tested with mojarra 4.0.5, same problem occurs

[BalusC]

Norepro. Nothing was "recently" changed in Mojarra related to that either. Mojarra is in the context of this problem merely the user of the HttpServletRequest not the implementor/provider of it. That's the servletcontainer itself (via jakarta.servlet.* implementations).

Just try a different servletcontainer to exclude the one and other. E.g. Glassfish, Liberty, Tomcat, etc. Or even an older version of WildFly with the latest Mojarra.

[BalusC]

Not an issue in Mojarra itself and work around was provided in original WildFly ticket https://issues.redhat.com/browse/WFLY-18821, so closing off.
