In some cases, I would need to retry a test only under some circumstances known at runtime. For example:

• Retry only on a specific exception or test failure message.
• Retry only in some JDK vendors.

I would expect the interface to be something like:

@Flaky(condition = { some closure here })

or perhaps something throwing a specific exception in the test:

flaky {
   // some assertion that may be flaky, and the test can be retried if this one failed
}
