Here comes\n<a href=\"http://www.kernel.org/pub/software/scm/git/docs/git-bisect.html\">git-bisect</a>.</p>\n\n<div class=\"language-shell highlighter-rouge\"><div class=\"highlight\"><pre class=\"highlight\"><code><span class=\"nv\">$ </span>git checkout <span class=\"nt\">-b</span> my-local-1.2 cdk1.2.x\n<span class=\"nv\">$ </span>git bisect start\n<span class=\"nv\">$ </span>git bisect bad\n<span class=\"nv\">$ </span>git bisect good 8219139e9236ab8036e9d08c13fcd0482d500c79\n</code></pre></div></div>\n\n<p>These lines indicate that the current version (HEAD) is broken, and that revision 8219139e9236ab8036e9d08c13fcd0482d500c79 was OK. Now,\n<code class=\"language-plaintext highlighter-rouge\">git-bisect</code> does the proper thing, and starts in the middle, allowing me to run my tests, and issue a <code class=\"language-plaintext highlighter-rouge\">git bisect bad</code> or\n<code class=\"language-plaintext highlighter-rouge\">git bisect good</code> depending on whether my test fails or not. The test I am running is:</p>\n\n<div class=\"language-shell highlighter-rouge\"><div class=\"highlight\"><pre class=\"highlight\"><code><span class=\"nv\">$ </span>ant clean dist-all test-dist-all jarTestdata\n<span class=\"nv\">$ </span>ant <span class=\"nt\">-Dmodule</span><span class=\"o\">=</span>smarts test-module\n<span class=\"nv\">$ </span>git bisect <span class=\"o\">[</span>good|bad]\n</code></pre></div></div>\n\n<p>So, if I had to inspect 1024 commits, I’d found the bad commit in 10 times running this test suite. For the culprit I was after it was\n6 times. The outcome was this commit, what I already suspected and emailed about to the\n<a href=\"https://lists.sourceforge.net/lists/listinfo/cdk-devel\">cdk-devel</a> mailing list:</p>\n\n<div class=\"language-plaintext highlighter-rouge\"><div class=\"highlight\"><pre class=\"highlight\"><code>[fa49ac603c36908f341b25d52a78435cdb8ca4d3] atomicNumber set as default (Integer) CDKConstants.UNSET\n</code></pre></div></div>",
