            Bug ID: 64904
           Summary: KeyPairGenerator.genKeyPair() fails if not explicitly
                    initialised
           Product: classpath
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: classpath
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gnu_andrew at member dot fsf.org

If genKeyPair() is called without an initialize method having being called
first, GNU Classpath attempts to generate a key using a key size of 0 and
fails.
