public class JavaExtensionFunctionCallCompiler
extends ToIteratorCompiler
```
Compiles a call to an old-style "reflexive" Java extension function. When compiled, the call is no longer reflexive, but is a direct call on the underlying method.

    Generate bytecode to evaluate the expression as a SequenceIterator Precondition: none. Postcondition: at execution time, the stack contains a SequenceIterator representing the result of the expression
    
    Specified by:
    
    compileToIterator in class ExpressionCompiler
    
    Parameters:
    
    compiler - the compiler service
    
    expression - the expression to be compiled
    
    Throws:
    
    CannotCompileException - if the expression cannot be compiled to bytecode
