Andy Clement a31f0bb3c0 Fix compilation of expressions using instanceof and primitives Prior to this commit the SpEL compiler would generate bad bytecode if the left hand operand of an instanceof was a primitive or if the right hand operand was a primitive type reference. With the fixes primitives on the left hand side are now correctly boxed and special handling is in place for when the right hand side is a primitive type reference. Using a primitive type reference on the right always causes the instanceof check to return false. Additionally a guard has been added such that compilation is not allowed when the right hand side of an expression is not a type reference. If it is, for example, a variable reference that evaluates to a type reference then that cannot be expressed in bytecode so compilation is not performed. Issue: SPR-14250	10 years ago

Andy Clement a31f0bb3c0 Fix compilation of expressions using instanceof and primitives

Prior to this commit the SpEL compiler would generate bad bytecode
if the left hand operand of an instanceof was a primitive or
if the right hand operand was a primitive type reference.
With the fixes primitives on the left hand side are now
correctly boxed and special handling is in place for when the
right hand side is a primitive type reference. Using a primitive
type reference on the right always causes the instanceof
check to return false.

Additionally a guard has been added such that compilation is
not allowed when the right hand side of an expression
is not a type reference. If it is, for example, a variable
reference that evaluates to a type reference then that
cannot be expressed in bytecode so compilation is not performed.
