Issue2770

I updated the JARs for BouncyCastle from 1.57 to 1.61 (see #2742), but now I get a regression on Java 7 (but not 8 or later). At the moment, I don't understand why, so will add a skip citing this issue.

I'm making this a low priority while it has only been observed for Java 7.

The new failure as follows:

======================================================================
ERROR: test_load_cert_chain (__main__.ContextTests)

PEMException: org.bouncycastle.openssl.PEMException: Unable to create OpenSSL PBDKF: PBKDF-OpenSSL SecretKeyFactory not available

This looks identical to #2594, the resolution of which I never really understood. (The JARs are on the classpath: from where else would one get a org.bouncycastle.openssl.PEMException?)

There's already a version-sensitive part to this test, making a special case of versions less than 9. This tweak is before we reach the new failure, and it doesn't seem to be about quite the same thing. But this I don't understand this tweak either, and removing does not cause failures, although it may have previously.

Same as #2858 (and not just Java 7).
