TestCryptoAdminCLI test failure when upgrading to JDK8 patch 171.

JDK8 patch 171 introduces a new feature:

New Features

security-libs/javax.crypto* Enhanced KeyStore Mechanisms*
A new security property named jceks.key.serialFilter has been introduced. If this filter is configured, the JCEKS KeyStore uses it during the deserialization of the encrypted Key object stored inside a SecretKeyEntry. If it is not configured or if the filter result is UNDECIDED (for example, none of the patterns match), then the filter configured by jdk.serialFilter is consulted.

If the system property jceks.key.serialFilter is also supplied, it supersedes the security property value defined here.

The filter pattern uses the same format as jdk.serialFilter. The default pattern allows java.lang.Enum, java.security.KeyRep, java.security.KeyRep$Type, and javax.crypto.spec.SecretKeySpec but rejects all the others.

Customers storing a SecretKey that does not serialize to the above types must modify the filter to make the key extractable.

We believe this causes some test failures:
