私はjava.nio.channels.FileLockをモックしようとしています。ここに私のコードを偽装して、それは例外を投げています。Mockito SubclassByteBuddyMockMaker.java:34 java.nio.channels.FIleLock例外
FileLock fileLock = Mockito.mock(FileLock.class);
Mockito.when(fileLock.isValid()).thenReturn(false);
のGradle：
compile 'junit:junit:4.12'
compile 'org.mockito:mockito-core:2.2.17'
provided 'org.hamcrest:hamcrest-junit:2.0.0.0'
