JR50653: JAVA INTEGRATION STEP FAILS WHEN HUGE JAR FILES ARE INVOLVED

Error description

  • You can model a Java integration step in a service flow to run
    arbitrary Java methods. However, the Java classes that are
    required to run these methods must be attached to the process
    application or toolkit as managed assets (server files).
    There is a special class loader that manages loading classes
    from managed assets.  Sometimes, the classes are swapped out of
    the cache and, as a result,  the classloader of the managed
    assets returns null instead of the resource data. The
    exception that you see depends on the Java method that is being
    called. The exception might indicate that a class-loading issue
    has occurred. For example, Java classes cannot be loaded
    correctly or property files are not loaded.
        This could also result in a temporary performance problem
    while the classes in the jar are being loaded.
    It may result in a WSVR0605W message like this
    [11/21/14 12:00:14:584 EST] 0000001f ThreadMonitor W
    WSVR0605W:
    Thread "WebContainer : 132" (00004752) has been active for
    760075 milliseconds and may be hung.  There is/are 199
    thread(s) in total in  the server that may be hung.

Local fix

  • You can prevent this issue from recurring by increasing the size
    of the managed asset class loader's resource map by adding the
    following lines to the 100Custom.xml file:
    
    <server> <|-- add if not already present-->
      <classloader-resource-map-size>size
      </classloader-resource-map-size>
    </server><|-- add if not already present-->
    
    The actual size depends on the total number of resources that
    are in your managed asset jar files.
    

Problem summary

  • The managed asset class loader maintains a cache of resources
    that are already loaded.
    If a managed asset jar file contains more resources than the
    maximum cache size can accept, a resource might not be loaded
    correctly and ?null? might be returned.
    

Problem conclusion

  • A fix is available that fixes this class loading issue.
