  .
  Typically, the class path class loader is the system class
  loader; however, this is not the case when the
  java.system.class.loader property is used.
  When this property is used, the JVM creates the class path class
  loader and then uses this class loader to instantiate the class
  identified by the java.system.class.loader property. This new
  class loader instance then becomes the system class loader.
  This instance will be the value returned by
  ClassLoader.getSystemClassLoader() and we assert that this
  instance, as the system class loader, should be the class loader
  used to load the classes identified by
  java.protocol.handler.pkgs.
  

Local fix

• N/A
  

Problem summary

• The problem use to happen as the classes identified by
  java.protocol.handler.pkgs system property use to get loaded
  with Application classloader even when java.system.class.loader
  system property is defined.
  

Problem conclusion

• The JDK code has been updated to make use of System classloader
  instead of Application classloader to load the classes
  identified by java.protocol.handler.pkgs system property.
