57 <application>OpenJDK</application> is an open-source implementation

75 OpenJDK is GPL'd code, with a special exception made for non-free
76 projects to use these classes in their proprietary products.
77 In similar fashion to the LGPL, which allows non-free programs to link
78 to libraries provided by free software, the
79 <ulink url="http://openjdk.java.net/legal/gplv2+ce.html">GNU
80 General Public License, version 2, with the Classpath Exception</ulink>
81 allows third party programs to use classes provided by free software
82 without the requirement that the third party software also be free. As
83 with the LGPL, any modifications made to the free software portions of a
84 third party application, must also be made freely available.

89 The <application>OpenJDK</application> source includes a very
90 thorough, open source test suite using the
91 <application>JTreg</application> test harness. The testing instructions
92 below allow to test the just built JDK for reasonable compatibility
93 with the proprietary Oracle JDK. However, in order for an independent
94 implementation to claim compatibility, it must pass a proprietary
95 <application>JCK/TCK</application> test suite. No claims of
96 compatibility, even partial compatibility, may be made without passing
97 an approved test suite.
98 </para>
99
100 <para>
101 Oracle does provide free community access, on a case by case basis, to
102 a closed toolkit to ensure 100% compatibility with its proprietary JDK.
103 Neither the binary version provided on the <xref linkend="java"/> page
104 nor the JVM built with the instructions below have been tested against
105 the <ulink
106 url="http://openjdk.java.net/groups/conformance/JckAccess/jck-access.html">
107 TCK</ulink>. Any version that is built using the instructions given,
108 cannot claim to be compatible with the proprietary JDK, without the
109 user applying for, and completing the compatibility tests themselves.
110 </para>
111
112 <para>
113 With that in mind, the binaries produced using this build method are
114 regularly tested against the TCK by the members listed on the site
115 above. In addition to the community license above, an educational,
116 non-commercial license for the TCK can be obtained from <ulink
117 url="http://www.oracle.com/technetwork/java/index-137188.html">

247 Before proceeding, you should ensure that your environment
248 <envar>PATH</envar> variable contains the location of the Java
249 compilers used for bootstrapping <application>OpenJDK</application>.
250 This is the only requirement for the environment. Modern Java

283 Testing will involve the interplay of pairs of JVMs using the
284 networking interface, so networking must be started. If it
285 isn't, not only will these tests fail, but the test cleanup
286 will leave orphaned JVMs running. There will be many of
287 them. Rebooting may be the easiest recovery.

292 Testing the newly built JVM involves several steps.
293 First, it is better to run the test suite in a frame buffer on a
294 different display, using Xvfb:

297<!-- Careful with the && below:
298"export DISPLAY=... && somecommand &" exports only DISPLAY to "somecommand"

360 Tests duration depends on various factors such as the network speed
361 and the number of concurrent VM, which is computed from the number
362 of cores and threads, and the amount of RAM installed. A maximum of
363 120 SBU has been observed, but it may be as <quote>low</quote> as 80 SBU.

367 The test results can be compared to <ulink
368 url="http://download.java.net/openjdk/testresults/8/">these
369 results</ulink>, although they usually are run on a newer version. Some
370 failures can be expected, the number of which depends on various
371 conditions, like whether the computer is connected to network. Also, some
372 tests may timeout if the machine is under load. Those are the reasons for
373 considering the tests optional, although we would rather recommend them.
374 </para>
375
376 <para>
377 Next some cleanup has to be done. The instructions below only stop the
378 frame buffer, but it has been reported that some java VM may be left
379 running after the tests, so it is necessary to check orphaned processes:
