Yes, the issue for `PBEWithSHA1AndRC2_40` when `SHA-1` is removed from `jdk.security.legacyAlgorithms` is because Algorithm Decomposer decomposes it to RC2_40 **accordingly** and Constraints map contains RC2 which is built based on `jdk.security.legacyAlgorithms`. Filed JDK-8301127 for this.
Filed JDK-8301130 to track adding MD2 to j`dk.security.legacyAlgorithms`.
