When run tests to cover https://bugs.openjdk.java.net/browse/JDK-8014061, we found application code fails to open .pack.gz files again.
It works fine with jre8-b113 and start to fail from jre8-b114

Steps to reproduce this bug:
0 Install jre8-b114
1 Set security level to medium since unsigned app will only allowed on medium
2 Launch unsinged app: javaws http://sqeweb.us.oracle.com/net/sqenfs-1/export1/comp/jsn/users/crystal/DO_NOT_REMOVE_ME/jrebug/packTests/jnlp/testOpenPackGz.jnlp

Application code that tries to execute
     try {
            URL url = new URL("jar:http://sqeweb.us.oracle.com/net/sqenfs-1/export1/comp/jsn/users/crystal/DO_NOT_REMOVE_ME/jrebug/packTests/classes/Data__V2.0.jar.pack.gz!/Data.txt");
            InputStream is = url.openStream();
            System.out.println("openStream succeeded");
out("PASS!!!");
setResult(true);
        } catch (Exception e) {
            System.err.println("openStream failed");
            System.err.println(e.toString());
out("Fail!!!");
setResult(false);
        }

3 An unsigned dialog will show up. Click "Run"
4 If app fails to open stream (openStream failed java.util.zip.ZipException: error in opening zip file), then this bug is reproduced.
