Auto-port 5.0: Isolate tests that modify available Security providers#16796
Merged
Conversation
Motivation: The `java.security.Security` providers list is a JVM-wide shared resource, and modifying the list at runtime can lead to problems where a provider that was available previously is suddenly removed. This can lead to `NoSuchAlgorithmException` and other issues, manifesting as flaky tests. Modification: Find all tests that modify the `Security` providers list, and make sure they're all `@Isolated`. Result: Less flaky build. (cherry picked from commit 4e578fc)
