[8u-dev] Request for approval to backport: 8158111: Make handling of 3rd party providers more stable

[Ivan Gerasimov]

Hello!

I'd like to backport this simple fix, which improves stability of 3rd 
party cripto providers, used in JSSE.

The unshuffled fix applies cleanly.

Would you please approve it?
