Question

I’m trying to retrieve entries from a Java KeyStore on Mac OSX 10.6. My code runs fine on Windows and Linux, but when I run it on OSX I get the following Exception:

java.lang.UnsupportedOperationException
    at java.security.KeyStoreSpi.engineGetEntry(KeyStoreSpi.java:466)
    at java.security.KeyStore.getEntry(KeyStore.java:1261)

Here’s my code:

String keyStorePath = ...
PasswordProtection pp = new PasswordProtection("password".toCharArray());
CallbackHandlerProtection chp = new CallbackHandlerProtection(
        new CallbackHandler() {

            @Override
            public void handle(Callback[] callbacks)
                    throws IOException, UnsupportedCallbackException {
                for (int i = 0; i < callbacks.length; i++) {
                    if (callbacks[i] instanceof PasswordCallback) {
                        PasswordCallback pc = (PasswordCallback) callbacks[i];
                        pc.setPassword("password".toCharArray());
                    }
                }
            }
        });

try {
    KeyStore.Builder kb = Builder.newInstance("JCEKS", null, new File(
            keyStorePath), chp);
    KeyStore ks = kb.getKeyStore();

    Enumeration<String> aliases = ks.aliases();
    while (aliases.hasMoreElements()) {
        String alias = aliases.nextElement();
        KeyStore.Entry entry = ks.getEntry(alias, chp);

    }
} catch (Exception e) {
    e.printStackTrace();
}

Any idea why this exception is being thrown on OSX? Is it a bug in the JVM on this OS? Anyone ever seen this before?

Looks to be a bug in Apple’s implementation of the JVM. I’ve submitted a bug report. Thanks for your help!
