<p>The <b>Java Research License</b> (<b>JRL</b>) is a software distribution <a href="License" title="License">license</a> created by <a href="Sun_Microsystems" title="Sun Microsystems">Sun</a> in an effort to simplify and relax the terms from the "research section" of the <a href="Sun_Community_Source_License" title="Sun Community Source License">Sun Community Source License</a>. Sun's <a href="Java_Platform%2C_Standard_Edition" title="Java Platform, Standard Edition">J2SE</a> 1.6.0, <i><a href="Java_(software_platform)" title="Java (software platform)">Mustang</a></i>, is licensed under the JRL as well as many projects at <a rel="nofollow" class="external text" href="https://web.archive.org/web/20100613131851/http://www.java.net/">Java.net</a>.
</p><p>The JRL was introduced in 2003 to try to "make things a lot more friendly to people doing academic research" into the Java language,<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> before the core of Java was made open source in 2006.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>
</p><p>Although the JRL has elements of an open source license, the terms forbid any commercial use and are thus incompatible with both the <a href="Free_Software_Definition" class="mw-redirect" title="Free Software Definition">Free Software Definition</a> and the <a href="Open_Source_Definition" class="mw-redirect" title="Open Source Definition">Open Source Definition</a>.
