java.security.UnrecoverableKeyException: Get Key failed: / by zero

I got this baby when my config like this on my conduit:

<sec:keyManagers >
   <sec:keyStore type="PKCS12" password="passwordForStore"
                  file="cert/key.pfx"/>
</sec:keyManagers>
  

Tip: ALWAYS put a password on the certificate which is inside the store, I exported it with internet options on windows and set a password. This goes for the keystore ONLY not the truststore.

Afterwards it looks like this:

<sec:keyManagers keyPassword="passwordForCertificate" >
   <sec:keyStore type="PKCS12" password="passwordForStore"
                  file="cert/key.pfx"/>
</sec:keyManagers>
