APAR status

  • Closed as program error.

Error description

  • The following exception might be seen during the application
    deployment and the ear expansion. Although this error happens
    during the deployment, the deployment would be completed. But
    if this error happens during the ear expansion, the expansion
    would fail.

Local fix

  • If the class which is causing the issue doesn't need to be
    scanned,
    we can skip the scan. For example, if the error in the problem
    description is causing by the ProcessIdUtil class in
    log4j-api-2.9.1.jar
    which is contained in the customer's application.
    If we add the following line in Ignore-Scanning-Packages
    section in <WAS_ROOT>/properties/amm.filter.properties.
    META-INF.versions.9.org.apache.logging.log4j.util, \
    we can avoid the issue.

    ****************************************************************
    Java V9 multi-release JARs contain Java V9 classes under the
    META-INF directory tree.  The existence of Java V9 classes
    causes application start to fail with an exception similar to
    the following:
    nnotationCon E   CWMDF0002E: Annotation processing failed
    with the following error:
    com.ibm.ws.metadata.annotations.AnnotationException: Annotation
    processing failed for class:

Problem conclusion

  • This problem is similar to PI89708 and PI93744.  The problem
    occurs in a different part of the WebSphere Application Server
    code.
    
    Java 9 multi-release JARs came along after WebSphere
    Application Server V9 was made available.  Therefore, the
    initial release of WebSphere Application Server has no support
    for them.
    
    This APAR along with PI89708 and PI93744 provide tolerance for
    multi-release JARs.  It does not provide support for the Java
    9 classes in the JARs, but the code is updated to ignore those
    classes.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 8.5.5.14 and 9.0.0.8.  Please refer to the
    Recommended Updates page for delivery information:
