#  @summary JDB allows evaluation of calls to static interface methods

#  @author Jaroslav Bachorik

#

#  @run shell/timeout=300 EvalInterfaceStatic.sh

#  The test exercises the ability to invoke static methods on interfaces.

#  Static interface methods are a new feature added in JDK8.

#

#  The test makes sure that it is, at all, possible to invoke an interface

#  static method and that the static methods are not inherited by extending

#  interfaces.
