visualvm fails with "No jdkhome found" on Ubuntu 15.10 with Oracle JDK : <p>I installed Oracle JDK from the <code>webupd8team/java</code> PPA, and then installed the <code>visualvm</code> package. When starting <code>visualvm</code>, I get the following error message:</p>

<pre><code>[beni:~]$ visualvm
No jdkhome found
</code></pre>

<p>My <code>$JAVA_HOME</code> is set correctly to <code>/usr/lib/jvm/java-7-oracle</code>.</p>

<p>Also, when starting <code>visualvm</code> with the <code>jdkhome</code> property set, I get the same error:</p>

<pre><code>[beni:~]$ visualvm --jdkhome $JAVA_HOME
No jdkhome found
</code></pre>
