Crypto stuff could be mocked in tests to prevent failures when there is no JCE

Hi,
I've an Ubuntu 15.04 and run with JVM Oracle JDK 1.8.60 and I got the followinf excpetion in mvn clean test

Tests run: 3, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.13 sec <<< FAILURE! - in org.springframework.cloud.config.server.encryption.EncryptionControllerMultiTextEncryptorTests
shouldEncryptUsingApplicationAndProfiles(org.springframework.cloud.config.server.encryption.EncryptionControllerMultiTextEncryptorTests)  Time elapsed: 0.13 sec  <<< ERROR!

    at org.springframework.cloud.config.server.encryption.EncryptionControllerMultiTextEncryptorTests.shouldEncryptUsingApplicationAndProfiles(EncryptionControllerMultiTextEncryptorTests.java:30)

with maven results as:

What can should I try to fix it?

Thanks

Run mvn clean test and inspect the failing EncryptionControllerMultiTextEncryptorTests, EncryptionControllerTests, KeyStoreTextEncryptorLocatorTests, and CipherEnvironmentEncryptorTests. Trace the calls through EncryptionController.checkEncryptorInstalled and determine how the crypto-dependent test behavior can be isolated; done means these listed tests pass in an environment without JCE.
