ERROR [IntrusionException] [SECURITY FAILURE Anonymous:null@unknown -> /ExampleApplication/IntrusionException] INTRUSION - Multiple (2x) encoding

I have this line of code in my project :

try {
    ESAPI.initialize("org.owasp.esapi.reference.DefaultSecurityConfiguration");
    value = ESAPIENCODER.canonicalize(value);
} catch (Throwable e) {
    LOG.warn("Invalid parameter value, setting to empty. Value: " + value, e);
    value = "";
}

I get the following error:

What does the warning mean and how can I get rid of it?
