Even without string concatenation, you receive the NumberFormat exception with
the following expression : 

${4+currentRow['a'].cellValue}

With ${4+currentRow['b'].cellValue}, the result is OK.

Why the empty string test is placed after the String instance test inside the
method org.apache.el.lang.ELArithmetic.coerce ?
