Hi Max,

I am not sure if SunMSCAPI has higher priority than SunJCE, SUN, etc on Windows. But this test is for SunMSCAPI provider, so we explicitly set this provider for Signature.

I remember Signature is able to automatically switch to the correct provider when its init(key) is called. Does this mean you don't need to care about Signature.getInstance(alg,provider)?

Thanks

Hello,

The test fails with "Key type not supported" error on Windows only with
SunMSCAPI provider. It happens because the test passes an incompatible
key object to Signature instance. Please see more details in

The following patch updates Chain.java (which is used by
SignedObjectChain.java) to use specified security provider for both key
generation and singing.

I ran all tests which depend on Chain.java on all generic platforms,
they worked fine.
