      Description

      ADDITIONAL SYSTEM INFORMATION :
      Windows 7 Professional SP1 x64
      JRE8 Updates tested: 191 and 192
      Deployment Ruleset rule:
      <rule>
      <id location="https://{SANITIZED}" />
      <action permission="run" version="1.6.0_24" />
      </rule>


      A DESCRIPTION OF THE PROBLEM :
      Update 191/192 appears to have made the JarFile.ensureInitialization() method available for implementation in the Java.Util.JarAccessImpl class.

      Update 191 JavaUtilJarAccessImpl.java source:

          public void ensureInitialization(JarFile jar) {
              jar.ensureInitialization();
          }

      In previous versions, JarFile.ensureInitialization() is a private method, so this becomes a problem when SSV saves the state for hand-off when a rule is defined that requires an applet to be handed off to an earlier JRE that does not support this method.

      REGRESSION : Last worked in version 8u181

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1 - Install a deployment rule set that specifies an applet is launched using an older java version. In our case, the applet (E-business Suite) requires Java version 1.6.0_24.
      2 - Launch the applet using Internet Explorer.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Applet loads using the defined earlier JRE version.
      ACTUAL -
      Applet fails to launch with exception java.lang.NoSuchMethodError: sun.misc.JavaUtilJarAccess.ensureInitialization(Ljava/util/jar/JarFile;) logged in the trace.

      CUSTOMER SUBMITTED WORKAROUND :
      Our only available workaround is to remove JRE version 1.8.0_191/192 and revert back to version 1.8.0_181.

      FREQUENCY : always
