A DESCRIPTION OF THE PROBLEM :
Additional information on reproducibility for JDK-8173460. I can reproduce the bug in different circumstances but with the same result. See steps to reproduce.

REGRESSION. Last worked in version 8u112

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
In my project

https://github.com/l-ra/openeet-java

it is easy to reproduce. Either build the project from the source or download latest snapshot from

https://github.com/l-ra/openeet/blob/master/releases/prerelease/openeet-lite-java8-20170115-0140.jar?raw=true

Using jdk update _121 run: java -jar openeet-lite-java8-20170115-0140.jar


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
should output something like this

===== END EET RESPONSE =====


ACTUAL -
Fails with exception (see error message field)

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
try {
KeyStore ks=KeyStore.getInstance("PKCS12");
ks.load(new ByteArrayInputStream(p12data), password);
Enumeration<String> aliases= ks.aliases();
while(aliases.hasMoreElements() ){
String alias=aliases.nextElement();
>>exception here>>> Key _key=ks.getKey(alias, password);
if (_key!=null){
Certificate _cert=ks.getCertificate(alias);
if (_cert!=null){
if ( _cert instanceof X509Certificate
&& _key instanceof RSAPrivateKey ){
key=(PrivateKey) _key;
certificate=(X509Certificate)_cert;
}
}
}
}
}
catch (Exception e ){
throw new IllegalArgumentException("Exception while loading p12 data",e);
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Import pkcs12 file into windows store and export again. Then loading works as expected.
