That's very weird. According to the JDK javadoc, there should be a
default iniitalization:
In case the client does not explicitly initialize the KeyPairGenerator
(via a call to an initialize method), each provider must supply (and
document) a default initialization. For example, the Sun provider uses a
default modulus size (keysize) of 1024 bits.
Perhaps this is happening because the generator is using a Random object
rather than a SecureRandom object. Random seeds itself using the current
time, which for two subsequent calls, may be the same.
Please check in your fix, and thanks for catching this!
