Description

In OgnlInvokeProcessor, we currently don't support static method calls as we always require a bean instance.

See this block of code in 2.10.3, starting on OgnlInvokeProcessor:247:

// loop and invoke each method
Object beanToCall = beanHolder.getBean();
// there must be a bean to call with, we currently does not support OGNL expressions on using purely static methods
if (beanToCall == null) {
    throw new IllegalArgumentException("Bean instance is null. OGNL bean expressions requires bean instances.");
}

Add support for these cases, especially handy if you use the method() expression frequently.
