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

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

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

246 Before proceeding, you should ensure that your environment

249 This is the only requirement for the environment. Modern Java

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

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

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

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

365 The test results can be compared to <ulink
366 url="http://download.java.net/openjdk/testresults/8/">these
367 results</ulink>, although they usually are run on a newer version. About
368 30 tests are known to fail, but the exact number depends on various
369 conditions, like whether the computer is connected to network, or to a
370 printer, and on the options given to configure
371 (<parameter>--enable-unlimited-crypto</parameter> is known to trigger
372 failures, but those come from the code in the tests, not from the
373 installation). Also, some tests may timeout if the machine is under load.
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:
380 </para>

502 of jobs for <command>make</command> equal to N. The default is the
503 result of a calculation involving the available memory and the number
504 of processors. Note that even if you specify N=1, some parallelization
505 may be used during the build. The SBU given above are with N=4, on

513 one is created. You can use the
