+- Added patch:
+  * java22.patch
+    + java.security.PrivateKey and java.security.PublicKey from
+      JDK version 22 extend the java.security.AsymmetricKey
+      interface, that contains default getParams() method.
+      The jce.javax.crypto.interfaces.DHPublicKey and
+      jce.javax.crypto.interfaces.DHPrivateKey thus inherits
+      abstract (from DHKey) and default for getParams(). This patch
+      fixes this problem the same way as OpenJDK did.
