Certificate error in javawebstart

I get the following at on a set of machines when trying to start our javawebstart program:

java.security.cert.CertificateParsingException: java.io.IOException: subject key, Unknown key spec: Invalid RSA modulus size


This problem only occurs in javawebstart 1.5.0_10, not in the other jre installations on the same machine (1.4.2_xx). The certificate we are using to sign the code is 1024bit.

I've tried to reproduce this problem in my test environment, trying both jre 1.5.0_10 and re 1.5.0_11, but without any luck reproducing the error.

does anybody have a hint on how to solve this problem?

does it only happen on a single machine?  Might be a problem with that installation.

It happes, as stated in my question, on a set of machines, located both in the US and Europe, but within the same company.

Yes. I'm trying to figure out if it is a problem with the installation, but since the users don't have admin privileges on their machines, it's quite hard to test.
