jenkins java plugin field gives Bad Message 414 reason: URI Too Long

Question

When field in my plugin is filled with about 5000 characters it gives error:

Bad Message 414
reason: URI Too Long

When I make it less a bit, it gives:

Bad Message 431
reason: Request Header Fields Too Large

config.jelly:

<f:entry field="field" title="Example">
   <f:textarea value="${it.getField()}"/>
</f:entry>

java:

private String field;
...
public FormValidation doCheckField(@QueryParameter String value)
            throws IOException, ServletException {
    if (value.length() == 0) {
        return FormValidation.error("Please set an input");
    } else {
        return FormValidation.ok();
    }
}

@ScaryWombat The point is to fix this issue, like changing the method of sending this data. And I am using Chrome. I assume this error message is given by plugin not by a browser. — A_Rybin, Jun 21 '17 at 06:23
Why the downvote on this one, I'm experiencing the exact same issue?!? Thank you for posting! — fusion27, May 21 '19 at 18:20

It was fixed by adding to Jenkins config

/etc/sysconfig/jenkins for default SLES installation
C:\Program Files (x86)\Jenkins\jenkins.xml in Windows

JENKINS_ARGS="--requestHeaderSize=32768"
