The API docs for ClassPrepareRequest.addClassFilter(String pattern) indicate
that events are to be restricted to classnames matching this pattern or
matching the name exactly if no '*' wildcard characters are used. We have found
that in certain cases when we want restrict events to a specific class using an
exact match pattern (ie. no wildcard characters are used), events are generated
for the restricted class as well as for any classes/interfaces that are part of
this class's class/interface hierarchy whose names start with the restricted
class name. For example:

class Test extends TestBase implements TestInterface {
   public static class main(String[] args) {}
}

class TestBase {}
interface TestInterface {}
interface TestNotUsed {}

ClassPrepareRequest req = eventRequestManager.createClassPrepareRequest()
req.addClassFilter("Test");
req.enable()

ClassPrepareEvents will be generated for Test as well as TestBase and
TestInterface but not TestNotUsed. It is as if we did addClassFilter("Test*")
except that only those classes/interfaces that are part of Test's
class/interface hierarchy have events generated for them.
