javax/net/ssl/ciphersuites/DisabledAlgorithms.java contains this fragment:

                // some of the certs in our test are weak; disable
                Security.setProperty("jdk.certpath.disabledAlgorithms", "");
                System.out.println("jdk.certpath.disabledAlgorithms = "
                        + Security.getProperty("jdk.cerpath.disabledAlgorithms"));

There's a typo in the property name on the last line - "cerpath" instead of "certpath". Does not affect the test result.
