Description
The P11Digest implementation should support cloning, if the underlying PKCS#11 library supports it. This means dynamically determining if the token supports C_GetOperationState() and C_SetOperationState() for digests and returning an instance of the appropriate P11Digest class as a result (that implements the Cloneable interface or that does not).

EVALUATION While testing the changes for supporting digest cloning functionality, I observed the following exceptions for SHA-256, SHA-384, and SHA-512 against Solaris softtoken impl: java.lang.CloneNotSupportedException at sun.security.pkcs11.P11Digest.clone(P11Digest.java:337) at java.security.MessageDigest$Delegate.clone(MessageDigest.java:543) at TestCloning.doCloning(TestCloning.java:83) at TestCloning.main(TestCloning.java:54) at PKCS11Test.premain(PKCS11Test.java:69) at PKCS11Test.testDefault(PKCS11Test.java:120) at PKCS11Test.main(PKCS11Test.java:79) at TestCloning.main(TestCloning.java:43) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at com.sun.javatest.regtest.MainWrapper$MainThread.run(MainWrapper.java:78) at java.lang.Thread.run(Thread.java:722) Caused by: sun.security.pkcs11.wrapper.PKCS11Exception: CKR_STATE_UNSAVEABLE at sun.security.pkcs11.wrapper.PKCS11.C_GetOperationState(Native Method) at sun.security.pkcs11.P11Digest.<init>(P11Digest.java:105) at sun.security.pkcs11.P11Digest.clone(P11Digest.java:335) ... 13 more May have to leave them disabled if Solaris softtoken impl does not support C_GetOperationState/C_SetOperationState() calls for these message digest algorithms.
