<h1>OpenJDK</h1>
<p>The open-source distributions based on <a href="https://en.wikipedia.org/wiki/OpenJDK" rel="nofollow noreferrer">OpenJDK</a> are available from various vendors.</p>
<p>The first that comes to mind is <a href="https://adoptopenjdk.net" rel="nofollow noreferrer">AdoptOpenJDK.net</a>, providing Java 8 with Update 282 currently.</p>
<p>Amazon provides <a href="https://docs.aws.amazon.com/corretto/latest/corretto-8-ug/downloads-list.html" rel="nofollow noreferrer">OpenJDK 8</a> in their <a href="https://aws.amazon.com/corretto/" rel="nofollow noreferrer">Corretto</a> offering.

<p><a href="https://www.azul.com/products/zulu-community/" rel="nofollow noreferrer">Zulu by Azul Systems</a> also provides <a href="https://www.azul.com/downloads/zulu-community/?&amp;version=java-8-lts" rel="nofollow noreferrer">OpenJDK 8</a>, <a href="https://assets.azul.com/files/Zulu-Enterprise-Data-Sheet-v5-15-19.pdf" rel="nofollow noreferrer">certified as Java</a>. They offer optional support plans as well.</p>
<p>See the <a href="https://stackoverflow.com/a/54737381/642706">nifty diagram</a> I made for sourcing Java 11. Some of those same vendors also provide Java 8, with and without paid support.</p>


<p>I'm trying to use <code>PDFRenderer</code> from <code>PDFBox</code> and works fine but it gives me a warning saying:</p>

</code></pre>

<p>which from what i understand it means i have to update to JDK 1.8.0_191 or higher to get the best experience out of the object.</p>

<p>my problem here is that how can I get the 1.8.0_191 or higher version of the JDK or any other solutions to implement, so that I won't get this warning and the <code>PDFRenderer</code> works faster. </p>
