UnrecoverableKeyException after migrating to AMD 64 bit

Question

Hi,
After migrating from 32 bit to AMD 64 bit, I'm getting an UnrecoverableKeyException when retrieving a key from an existing keystore. The provider is Bouncy Castle.
I have reproduced the problem using only keytool on the command line.
I wanted keytool to attempt to retrieve the key so I tried cloning it with -keyclone.
This is the result running java version 1.5.0_06 on 32 bit
colin@warthog /tmp $ keytool -keyclone -alias symmetricKey -keypass "xxxxxxx" -new "password" -keystore ./symmetricKeyStore -storepass "xxxxxxx" -storetype BKS
Enter destination alias name: dummy
keytool error: java.lang.Exception: Recovered key is not a private key
Now here is the result running java version 1.5.0_06 on AMD 64 bit
jboss@mrmessy:/tmp$ keytool -keyclone -alias symmetricKey -keypass "xxxxxxx" -new "password" -keystore ./symmetricKeyStore -storepass "xxxxxxx" -storetype BKS
Enter destination alias name: dummy
keytool error: java.security.UnrecoverableKeyException: no match
The "Recovered key is not a private key" exception should be what I get on 64 bit also but I get the UnrecoverableKeyException which is what I get in my java code aswell. So it is happening both in my java code and in keytool.
I'm not really sure how to proceed from here and I was hoping someone here might point me in the direction. Even if you could just give me some better testing ideas, I'd appreciate it.
Regards,
Colin Daly.

It was simply the java install on the server did not have the unrestricted policy files from jce_policy-1_5_0.zip intalled. If you ever have problems with bouncycastle, I recommend running their regression tests before going any further...
