Since a9d1ad4 JWK.publicKey()/privateKey() resolve the key through signingAlgorithm.unwrap(). EC keys are wrapped by wrapECAlgo to convert between JWS and ASN.1 signatures, and that wrapper did not override unwrap(), so the chain stopped at the wrapper and both accessors returned null for ES256/ES384/ES512/ES256K keys (JSON JWK, PEM and keystore alike). The wrapper now delegates unwrap() to the wrapped algorithm. JWKTest gains EC public/private (JSON and PEM) assertions with RSA as control. Fixes eclipse-vertx#762

Regression from a9d1ad4:
JWK.publicKey()/privateKey()now go throughsigningAlgorithm.unwrap(), but the anonymous EC wrapper created byJWK.wrapECAlgo(...)did not overrideunwrap(), so for every EC key (ES256/ES384/ES512/ES256K, from JSON JWK, PEM or keystore) the chain stopped at the wrapper and both accessors returnednull. RSA/PS/EdDSA keys were unaffected because they are not wrapped.Fix: the wrapper delegates
unwrap()to the wrappedDigitalSigningAlgorithm(one method). Nothing else about the wrapper changes — signing/verification still convert between JWS R+S and ASN.1 as before.Tests:
JWKTestgainspublicECExposesPublicKey,privateECExposesKeyPair,pemECExposesKeys(all failed before the fix) andpemRSAExposesPublicKeyas a control. vertx-auth-common, vertx-auth-jwt and vertx-auth-oauth2 suites are green locally.
