> org.apache.harmony.crypto.utils.AlgNameMapper in some cases overrides default hardcoded mappings which are not to be overridden (according to description in comments) by the ones from providers. 
> The method isOID(String) of the class determines if the given algorithm name is an OID or not in an incorrect way. 
> import org.apache.harmony.crypto.utils.AlgNameMapper;
> public class AlgNameMapperTest {
>     public static void main(String[] args) {
>         // check a hardcoded mapping
>         String standardName = AlgNameMapper.getStandardName("PBEWITHSHAAND40BITRC2-CBC");
>         if (!standardName.equalsIgnoreCase("pbeWithSHAAnd40BitRC2-CBC")){
>             System.out.println("getStandardName(..) FAILED!");
>         }
>         
>         // check if the algorithm name is an OID
>         if (AlgNameMapper.isOID("not.an.oid")){
>             System.out.println("isOID(..) FAILED!");
>         }
>     } 
> }
> The patch included resolves the problems noted. It also widens the functionality of the mapper to search for signature mappings in providers (currently only Cipher and AlgorithmParameters are searched).
