    This macro should be usable as a drop-in replacement for java_library.

    The additional arguments are given the bndlib tool to generate an OSGi-compliant manifest file.
    See [bnd documentation](https://bnd.bndtools.org/chapters/110-introduction.html)

    Takes all the args that are standard for a java_library target plus the following.
    Args:
        bundle_description: (required) The Bundle-Description header defines a short
            description of this bundle.
        automatic_module_name: (required) The Automatic-Module-Name header that represents
            the name of the module when this bundle is used as an automatic
            module.
        bundle_name: (required) The Bundle-Name header defines a readable name for this
            bundle. This should be a short, human-readable name that can
            contain spaces.
        bundle_symbolic_name: (required) The Bundle-SymbolicName header specifies a
            non-localizable name for this bundle. The bundle symbolic name
            together with a version must identify a unique bundle though it can
            be installed multiple times in a framework. The bundle symbolic
            name should be based on the reverse domain name convention.
        bundle_additional_exports: The Export-Package header contains a
            declaration of exported packages. These are additional export
            package statements to be added before the default wildcard export
            "*;version={$Bundle-Version}".
        bundle_additional_imports: The Import-Package header declares the
            imported packages for this bundle. These are additional import
            package statements to be added before the default wildcard import
            "*".
        **kwargs: Additional key-word arguments that are passed to the internal
            java_library target.
