Change Bootstrap Entries in Eclipse Run Configuration
<p>I'm currently migrating from Java 1.7 to Java 1.8 and I'm facing a little problem with my Run Configuration in Eclipse: On the <em>Classpath</em> tab, there are two sections (namely <em>Bootstrap Entries</em> and <em>User Entries</em>). In the <em>Bootstrap Entries</em> section, it says <strong>JRE System Library [JavaSE-1.7]</strong>.</p>

<p>However, I set Java 1.8 as my default runtime environment in Eclipse's preferences already. I do have several Run Configurations and some already point to a 1.8 JRE, I previously installed. But it is not possible to edit the entry in the Run Configuration dialog.</p>

<p>So, I wonder:</p>

<ul>
<li>What actually is a <em>Bootstrap Entry</em>?</li>
<li>Where does it come from?</li>
<li>Where can I modify it from 1.7 to 1.8?</li>
</ul>
