Error description

  • In the 16.0.0.2 release of WebSphere Liberty, a third party
    library called Apache Commons Compress was added to JVM's
    classpath.  This can cause problems for applications or
    server
    extensions that attempt to make use of this third party
    library
    - as it will not be loaded by the JVM's application
    classloader
    rather than the application/extension's expected
    classloader.
    
    It may be possible to work around this problem by putting
    the
    Commons Compress JAR files into a common library that uses
    parent last delegation, but this is not generally a best
    practice.
    

Local fix

  • Put the Commons Compress JAR files into a common library that
    uses parent last delegation

    practice.
    

Problem conclusion

  • The fix for this APAR removes the Commons Compress classes from
    the Liberty kernel boot bundle which is in the JVM's classpath
    and puts it into a separate bundle which is loaded only when
    performing server packaging operations.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 16.0.0.3.  Please refer to the Recommended Updates page for
