Add the following JAVA_OPTS setting to the release notes for 2.9:
At least one JSF tool (forums) requires it when running it in Tomcat 7.
Matt Jones: "There were one more strict changed to be true between 5.5 & 7.0 org.apache.jasper.compiler.Parser.STRICT_WHITESPACE
(If false the requirements for whitespace before an attribute name will be relaxed so that the lack of whitespace will not cause an error. Default is the spec value which is true)
Perhaps because the code isn't <%@ include or using <jsp:include there it's causing an error now?"
Matt's suspicion was confirmed by David Horwitz.
