DRS certificate based rule does not match with Java WS Application compressed by pack200

FULL PRODUCT VERSION :
JDK 9 b57, JDK 8u31 b13, JDK 7u75 b13

ADDITIONAL OS VERSION INFORMATION :
MS Windows 7 OS

A DESCRIPTION OF THE PROBLEM :
Deployment Rule Set (DRS) rule based on "certificate" element does not match Java Web Start (WS) application, when its JAR files are compressed by pack200 tool, and "<property name="jnlp.packEnabled" value="true"/>" property/value pair is specified in JNLP file of the Java WS application.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Upload "TestCase.jar.pack.gz", "DRSBlocksJavaWSAppInPack200Archive.jnlp" files from the attached archive file "DRSBlocksJavaWSAppInPack200Archive.zip" with the test case to the same directory on an accessible web server.
2. Edit "codebase" attribute value in the uploaded JNLP file "DRSBlocksJavaWSAppInPack200Archive.jnlp" to reflect a URL to the directory, where the file was uploaded.
3. Install JRE 9, or JRE 8, or JRE 7 to be tested.
4. Copy "DeploymentRuleSet.jar" file of the test case to the directory "C:\Windows\Sun\Java\Deployment".
5. Import "deploymentruleset.cer" certificate from the test case through "Java Control Panel -> Security -> Manage Certificates... -> Certificate type: Signer CA -> User -> Import".
6. Open Internet Explorer (IE) web browser and load Java WS test case by accessing the uploaded in the point #1 "DRSBlocksJavaWSAppInPack200Archive.jnlp" file. The bug is reproduced, if Java WS application is blocked by DRS.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Full Java WS logs with the bug reproduced using JRE 9 b57 by means of the test case are available in the attached "Logs.zip" archive file.
