    ****************************************************************
    Provide a switch using Java system property to skip creating
    WebSphere Application Server's own https URL Stream Handler.
    There was a change with IBM SDK SP9 FP1, the Java code was
    updated to increase security.
    When WebSphere tries to create its own https stream handler,
    a URL stream handler is loaded from specified URL location
    which now requires another URL stream handler again. This
    results in recursive call and cause stack overflow.
    This issue has been seen only when the Application
    Server client is launched using Java Web Start.
    Earlier, the Application Server needed to create https
    stream handler.  Now that Java provides default https Stream
    Handler, the Application Server can provide option not to
    create its own handler to keep from this NoClassDefFoundError.
    To skip creating the https stream handler,
    following Java System property needs to be set to "false".
    Java System property:
    com.ibm.websphere.ssl.provider.create.https.handler
    Default value : true
    

Problem conclusion

Temporary fix

  • Inside application code, load the class explicitly in the
    code prior to the error.
    Class.forName("com.ibm.ws.runtime.util.utilHandlerClass");
