JweRsaKeyEncryptionDecryptorImpl.Decrypt passed the JWE's initialization vector to cipher.AEAD.Open without checking its length. The Go standard library panics rather than returning an error when a GCM nonce is not exactly NonceSize() bytes, so a JWE carrying a wrong-sized IV crashes the decrypting goroutine.
