Error description

  • When calling the normalizeUnixStylePath method with a path
    such as "//META-INF/resources/css", this path should be
    normalized to "/META-INF/resources/css" - with the leading
    double slash modified to a single slash.  This is currently
    not happening in all cases.
    
    Additionally, the checkCase method in PathUtils is behaving
    inconsistently.  It is always returning true on case
    sensitive file systems, but it may return false on case
    insensitive file systems when he case of the path does not
    match the case of the specified file.  This behavior should
    be the reverse - it should always return true for case
    insensitive file systems, and return false on case sensitive
    file systems when the case of the path does not match the
    case of the specified file.

    false on case sensitive file systems when the case of the path
    does not match the case of the specified file.
    

Problem conclusion

  • The fix for this APAR is to ensure that leading double slashes
    are converting to leading single slashes, and that the checkCase
    method always returns true for case insensitive file systems and
    checks the case for case sensitive file systems.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.2.  Please refer to the Recommended Updates page for
