CVE-2011-2730: EL expressions double evaluation

When a container supports Expression Language (EL), this package evaluates EL expressions in tags twice, which allows remote attackers to obtain sensitive information via a name attribute in a spring:hasBindErrors tag; path attribute in a spring:bind or spring:nestedpath tag; arguments, code, text, var, scope, or message attribute in a spring:message or spring:theme tag; or var, scope, or value attribute in a spring:transform tag, aka Expression Language Injection.
