<p>Hi there,</p>
<p> </p>
<p>I just downloaded birt runtime birt-runtime-4.5.0-20150609.zip and installed under JBoss.</p>
<p> </p>
<p>the following is the env info:</p>
<p>Java version: 1.6.0_10,Sun Microsystems Inc.</p>
<div>OS-System: SunOS 5.10,sparcv9</div>
<div>
<div>jboss.home.dir: /opt/jboss_dist/jboss-portal-2.6.2.GA</div>
<div>
<div>sun.arch.data.model: 64</div>
<div> </div>
<div>even the Jboss we are using is old, but we could run birt 4.4.2 successfully.</div>
<div> </div>
<div>When I install birt 4.5, I got java.lang.UnsupportedClassVersionError. Is birt 4.5 compiled using java 1.7? What should I do to fix it?</div>
<div> </div>
<div> </div>
