Pushes the abstract type corresponding to the given descriptor on the output frame stack.

@param symbolTable the type table to use to lookup and store type {@link Symbol}.
@param descriptor a type or method descriptor (in which case its return type is pushed).
Pushes the abstract type corresponding to the given descriptor on the output frame stack .
