Error description

  • Error Message: Customer use to get NullPointerException while
    launching a WebStart Application via IBM 7.0 Webstart using
    Oracle 6.0 JRE.
    .
    Stack Trace: java.lang.NullPointerException
    at
    com.sun.deploy.services.WPlatformService.getSecureRandom(Unknown
    Source)
    at com.sun.deploy.cache.Cache.getSecureRandom(Unknown Source)

    a:251)
    .
    The reported issue occurs only in the case when two Java vendors
    involved in the execution of WebStart application.This scenario
    can be acheived by adding one Vendors JRE in other Vendors Java
    Control Panel and use that JRE to run the Webstart application,
    for eg. adding Oracle JRE in IBM Java Control Panel.
    

Local fix

  • N/A
    

Problem summary

  • The security providers will be specific to Java Vendors and if
    there is a combination of Java Vendors involved in launching a
    WebStart application then Security.getProvider API will return
    null. As JDK is not taking care of null, it use to end up with
    NullPointerException.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR3
    .
    The JVM has been updated to take care of null return by
    Security.getProvider API when when two Java vendors are involved
    in the execution of WebStart application.
