how to fix?

I recommend that you download and install the Oracle/Sun JDK instead of using OpenJDK.

Although OpenJDK is a lot more complete implementation of the Java spec than it used to be, apparently it still falls short when used with Tomcat7.

If you download and install the RPM version, it will place the JDK in the /usr/java directory and you can set JAVA_HOME using either the specific version or just set it to /usr/java/latest.
