Correct behavior verified as follows:

    lxc launch ubuntu-daily:xenial tester && lxc exec tester bash
    apt update && apt dist-upgrade -y && apt install -y tomcat8 && mkdir -p /var/lib/tomcat8/webapps/test && echo '<%@ page contentType="text/html;charset=UTF-8" language="java" %>
    <html>
    <head>
        <title>$Title$</title>
    </head>
    <body>
    <%
        Class.forName("org");
    %>
    </body>
    </html>
    ' >/var/lib/tomcat8/webapps/test/test.jsp &&
    service tomcat8 restart &&
    curl localhost:8080/test/test.jsp

This results in the following erroneous jsp exception:

java.lang.StringIndexOutOfBoundsException: String index out of range: 3
    java.lang.String.charAt(String.java:658)
    org.apache.catalina.loader.WebappClassLoaderBase.filter(WebappClassLoaderBase.java:2802)

Upgrade to the version in proposed and re-run the test:

    echo "deb http://archive.ubuntu.com/ubuntu xenial-proposed main restricted" >>/etc/apt/sources.list &&
    apt update &&
    apt dist-upgrade -y &&
    curl localhost:8080/test/test.jsp

This results in a jsp exception with a proper root cause:
