AndroidJUnitRunner doesn't run JUnit test with clear JUnit4 style

What steps will reproduce the problem?
1. My buid.gradle looks like:
buildscript {
...
}
apply plugin: 'com.android.application'

repositories {
...
}

android {
    compileSdkVersion 21
    buildToolsVersion '21'

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 19

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    packagingOptions {
    ...
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }

    productFlavors {
    ...
    }

    buildTypes {
    ...
    }
}

dependencies {
    ...
    androidTestCompile ('com.android.support.test.espresso:espresso-core:2.0') {}
    androidTestCompile ('com.android.support.test:testing-support-lib:0.1') {}
}

2. I have created simple JUnit test class using clear JUnit4 syntax 
(DemoPrinciplesOfUnitTesting.java).
3. I started tests but my class was not added to test suite.
4. When I renamed method thisIsTheTestTwo() to test_thisIsTheTestTwo() (JUnit 3 
syntax) I have receved expected result.
4. I have received the same results by starting tests with "./gradlew 
connectedCheck" console command.

What is the expected output? What do you see instead?
Expected output:
V/DEMO﹕ Setup CLASS
V/DEMO﹕ Setup test
V/DEMO﹕ Perform test 2
V/DEMO﹕ Tear down test
V/DEMO﹕ Setup test
V/DEMO﹕ Perform test 1
V/DEMO﹕ Tear down test
V/DEMO﹕ Setup test
V/DEMO﹕ Perform test 3
V/DEMO﹕ Tear down test
V/DEMO﹕ Tear down CLASS

But I see instead:
nothing

What version of the product are you using? On what operating system?
Espresso 2.0
Android Studio 1.0.2
Gradle wrapper 2.2.1
OS Ubuntu 12.04 LTS x64

        Log.v(DEMO_TAG, "Tear down CLASS");
    }
}
