To determine actual types of parameters for class passed in as lambda to
step definition, code uses old Sun ConstantPool to look for dynamic
linking data.  Previously these values were found at index size()-2;
however as of 1.8.0_60 the location appears to have changed to size()-3.
Given that the following indexes appear to have empty/invalid values,
instead iterate downward from end to find first valid value and use for
parameter type determination.

Conform to project coding standards regarding tabs, line feeds and
encoding.
