110 | thorough, open source test suite using the

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

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

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

114 | implementation to claim compatibility, it must pass a proprietary
|

115 | <application>JCK/TCK</application> test suite. No claims of
