Detected references to weak named curves that have been removed

In Java 14, weak named curves were disabled by default for TLS, CertPath, and Signed Jar. In Java 15, the weak named curves were were disabled by default in the native SunEC implementation. In Java 16 the implementation for the weak named curves was removed.

The following curves were removed:

secp112r1, secp112r2, secp128r1, secp128r2, secp160k1, secp160r1, secp160r2, secp192k1, secp192r1, secp224k1, secp224r1, secp256k1, sect113r1, sect113r2, sect131r1, sect131r2, sect163k1, sect163r1, sect163r2, sect193r1, sect193r2, sect233k1, sect233r1, sect239k1, sect283k1, sect283r1, sect409k1, sect409r1, sect571k1, sect571r1, X9.62 c2tnb191v1, X9.62 c2tnb191v2, X9.62 c2tnb191v3, X9.62 c2tnb239v1, X9.62 c2tnb239v2, X9.62 c2tnb239v3, X9.62 c2tnb359v1, X9.62 c2tnb431r1, X9.62 prime192v2, X9.62 prime192v3, X9.62 prime239v1, X9.62 prime239v2, X9.62 prime239v3, brainpoolP256r1, brainpoolP320r1, brainpoolP384r1, brainpoolP512r1

These curves should no longer be used, but if they are required by the application a third-party alternative must be used.
