67 | The <application>OpenJDK</application> source includes a very

68 | thorough, open source test suite using the

69 | <application>JTreg</application> test harness. The testing instructions

70 | below allow to test the just built JDK for reasonable compatibility

71 | with the proprietary Oracle JDK. However, in order for an independent

72 | implementation to claim compatibility, it must pass a proprietary
|
---|
73 | <application>JCK/TCK</application> test suite. No claims of
