@Ignore is a junit annotation that prevents a test being run. The value of the annotation is only a comment and is not interpreted by junit.

This is an Oracle-internal jira instance. The bug it relates to is described at https://github.com/oracle/graal/pull/299#pullrequestreview-104037056.

You can replace the @Ignore on the test method with something like:

        Assume.assumeFalse(getTarget().arch instanceof AMD64);

Yudi: Is that what Dmitry should do while you're working on the fix for GR-8748?
