    Bug Fixes of Interest
    The following bugs have been addressed in this release:

    4835830: Add per-service proxy preparer support
    Per-service proxy preparer support has been added to NonActivatableServiceDescriptor and SharedActivatableServiceDescriptor via constructor overloads that take proxy preparer parameters. This allows users to individually prepare the service proxies returned by service starter framework.

    4856937: Service starter should permit specifying dynamic policy provider
    ActivateWrapper supports the the java.security.Security property org.apache.river.start.servicePolicyProvider, which allows users to specify the fully qualified class name of a dynamic policy provider to use for wrapping individual service policies in a "shared" environment. A custom service policy provider can be very useful when trying to debug security related issues. See the start package documentation for more detail.

    4858623: change ExportClassLoader to use context class loader for parent
    ActivateWrapper.ExportClassLoader now uses the calling context's class loader as its parent (versus the application classpath, used previously). This allows "container" applications more control over the class loader hierarchy used when launching services.

    6211452: change ActivateWrapper.ExportClassLoader to subclass PreferredClassLoader
    ActivateWrapper.ExportClassLoader now extends PreferredClassLoader instead of URLClassLoader. A service can now specify a preferred list for its import class path, to ensure that any classes that need to be annotated with the server's codebase get loaded by the server's class loader rather than accidentally being resolved in the container.

    4868839: Make utility class constructors private
    The following utility classes simply contain static methods and are not meant to be instantiated:
    • ClassLoaderUtil
    • DestroySharedGroup
    • HTTPDStatus
    To ensure this, private constructors have been added to each of the above classes.

    4936006: ServiceDescriptor's should support non-file-based classpath entries
    The importCodebase parameter in the constructors for NonActivatableServiceDescriptor and SharedActivatableServiceDescriptor now support either:
    • a space delimited set of URL(s) representing a codebase or
    • a File.pathSeparator delimited set of class paths.
