Compatibility matrix is incorrect

The compatibility matrix indicates plugin version 3.2.1 is compatible with Keycloak version 21.0.2. We are in the process of upgrading to BigBang 1.57.1 and found this was inaccurate. Neither 3.2.1 nor the plugin version used with the previous BigBang Keycloak version (plugin 3.0.0) work with Keycloak 21.0.2. Plugin version 3.2.0 IS compatible with Keycloak 21.0.2.

If we try to use plugin 3.2.1 with Keycloak 21.0.2, clicking the self-register link instantly fails with an internal server error (500). Keycloak logs show a message like:

ERROR...KeycloakErrorHandler...Uncaught server error...NoSuchMethodError...getHttpRequest()...

UPDATE: The compatibility matrix IS incorrect, but the solution I suggested at first above is not right. Rather than removing the compatibility, the issues should be corrected. See sister issue #36 (closed)
