Test Scenario
=================
statically register JsafeJCE provider into java.security
that means add the following line into $JAVA_HOME/jre/lib/security/java.security
security.provider.6=com.rsa.jsafe.provider.JsafeJCE
Then we try to use keytool command

How to Reproduce
=================
1. keytool -genkey -alias another -keyalg myKeyAlgo -keysize 768 -sigalg DSS -dname cn=YunKe -keypass keypasswd -keystore mykeystore -storepass storepasswd
2. you will see this --
Exception in thread "main" java.lang.LinkageError: duplicate class definition: com/rsa/jsafe/provider/JsafeJCE

Actually, we expect the following result --
keytool error: java.security.NoSuchAlgorithmException: MYKEYALGO KeyPairGenerator not available

Note:
It failed with Merlin and Hopper, but Passed with Ladybird (JDK 1.3.1)
