When verify fix of JDK-8135115, I found that "ruleset version=1.0"+"jnlp-checksum" issue is still there.

Steps to reproduce:
1. Import self ca cert to JCP -> Security -> Manage Certificates -> Singer CA.
    http://kgb.us.oracle.com:8080/DRS13Manual/lib/self.valid.cert
2. Set up DeploymentRuleSet.jar:
    http://kgb.us.oracle.com:8080/DRS13Manual/lib/DeploymentRuleSet.jar.run-Jnlp-Checksum-Version-kgb/DeploymentRuleSet.jar
    It sets rule set version to 1.0 while with jnlp-checksum element in ruleset.xml
    For rule set content, see http://kgb.us.oracle.com:8080/DRS13Manual/lib/DeploymentRuleSet.jar.run-Jnlp-Checksum-Version-kgb/ruleset.xml
3. Open browser and load http://kgb.us.oracle.com:8080/DRS13Manual/html/testApps.html
4. Launch casinged jnlp by clicking on the link testCertsignedAllpermissionJNLPNoHref.jnlp from a browser
5. If a valid security warning dialog shows up, then this issue is reproduced.
Expected behavior:
An application blocked dialog saying "Exception parsing Deployment Rule Set file" should show up.
