I tried using `-keyalg PBEWithSHA1AndRC2_40` and removed `SHA-1` from `jdk.security.legacyAlgorithms` and see no warning. It looks like the disabled algorithm decomposer cannot extract "RC2" from the algorithm name.

Also, since this check only looks at `jdk.security.legacyAlgorithms`, shall we add other disabled algorithms here as well? Like MD2.
