A DESCRIPTION OF THE PROBLEM :
KeyStore PKCS12 does not return stored certificate by alias if alias contains upper case characters.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create KeyStore:
KeysStore keyStore = KeyStore.getInstance("PKCS12");

Store certificate:
keyStore.setCertificateEntry("testCert", certificate);

Get Certificate don't work:
keyStore.getCertificate("testCert"); // null

boolean a = keyStore.entryInstanceOf("testCert", KeyStore.PrivateKeyEntry.class); // false
a = keyStore.entryInstanceOf("testCert", KeyStore.TrustedCertificateEntry.class); // false
a = keyStore.entryInstanceOf("testCert", KeyStore.SecretKeyEntry.class); // false

keyStore.getEntry("testCert", new KeyStore.PasswordProtection(password)); // null

keyStore.aliases(); // contain "testCert"

keyStore.containsAlias("testCert"); // false



REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
package sun.security.pkcs12;

trouble in PKCS12KeyStore.class

    public boolean engineContainsAlias(String var1) {
        return this.entries.containsKey(var1.toLowerCase(Locale.ENGLISH));
    }

because in setCertEntry at this.entries.put(var1, var5);
var1 not lower cased;
