 <p>To run these tests correctly, additional parameters for the correct docker image are required on Ubuntu 18.04 by using <code>JAVA_OPTIONS</code>.</p>
 <pre><code>$ make test TEST=&quot;jtreg:test/hotspot/jtreg/containers/docker&quot; JTREG=&quot;JAVA_OPTIONS=-Djdk.test.docker.image.name=ubuntu -Djdk.test.docker.image.version=latest&quot;</code></pre>
+<h3 id="non-us-locale">Non-US locale</h3>
+<p>If your locale is non-US, some tests are likely to fail. To work around this you can set the locale to US. On Unix platforms simply setting <code>LANG=&quot;en_US&quot;</code> in the environment before running tests should work. On Windows, setting <code>JTREG=&quot;VM_OPTIONS=-Duser.language=en -Duser.country=US&quot;</code> helps for most, but not all test cases. For example:</p>
+<pre><code>$ export LANG=&quot;en_US&quot; &amp;&amp; make test TEST=...
+$ make test JTREG=&quot;VM_OPTIONS=-Duser.language=en -Duser.country=US&quot; TEST=...</code></pre>
