Local fix

  • Use  "-Xnosplash" or do "javaws -clearcache" before launching
    

Problem summary

  • 1) Clear the cache by deleting .java folder "rm -rf .java"2)
    Launch webstart application and stop3) Launch webstart
    application4) dumps core
    

Problem conclusion

  • Issue is fix in java8sr1. Root cause of the issue is malloc(0)
    returns NULL on AIX but return aribitary pointer on non AIX. So
    there was an assumption made and null character is placed by
    deferencing returned pointer which results in dumping core.
    Assumption is corrected now.
    .
