#  @test
#  @bug 8031195
#  @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.
