JavaParser: Where is the Java grammar definition?
<p>Where can I get the BNF-style Java 1.8 grammar that <a href="https://github.com/javaparser/javaparser" rel="nofollow">JavaParser</a> is <em>actually</em> using to parse Java code?</p>

<p>There's a <code>java_1_8.jj</code> file in JavaParser's codebase automatically generated by <code>javacc</code>, but no sight of the grammar file used to generate this <code>.jj</code> file.</p>
