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?
