Two new system properties have been added to customize the TLS signature schemes in JDK. `jdk.tls.client.SignatureSchemes` has been added for the TLS client side, and `jdk.tls.server.SignatureSchemes` has been added for the server side. Each system property contains a comma-separated list of supported signature scheme names specifying the signature schemes that could be used for the TLS connections. The names are described in the "Signature Schemes" section of the *Java Security Standard Algorithm Names Specification*.
