title: Tomcat 7 with Java 8 on Windows and Linux
body: <p>I got the following trouble:</p>
  
  <p>I wanna use Java Servlet built on target Java-8 with Apache Tomcat 7.0.54.</p>
  
  <p>When I run it on my local machine (Win-64, jdk build 1.8.0-b132) it works perfectly.</p>
  
  <p>But when I deploy it on production (Debian GNU/Linux 7.5 (wheezy), jdk build 1.8.0-b132, Tomcat 7.0.54-2) it throws:</p>
  
  <pre><code>Unsupported major.minor version 52.0 (unable to load class ru.tomtrix.fvds.servlets.ItemServlet)
  </code></pre>
  
  <p>... that means unsupported Java-8 classes.
  So what's going wrong to Windows and Linux instances of the <strong>same</strong> version of Tomcat?</p>
