Description

JDK 5.0 changed the signature of Method.invoke() to using varargs for the second argument. The ExpressionEvaluatorProxy for JSP 2.1 passes null, which presumably gets coerced into new Object[]

{ null }

by the compiler. This causes an exception because the runtime arguments for JspApplicationContexts.getExpressionFactory() do not match its signature. Passing an empty array Object[] {} to Method.invoke() resolves this ambiguity.
