ESTK ignores try/catch during debugging

Question

When running under photoshop, try/catch error doesn't stop execution (has it should).
Not as when running under ESTK for debugging.On ESTK, try/catch is ignored and the error doesn't catch for debug.
I'm using ESTK 4.0.0.1 under CC2014 on windows7

Answer 1

For example, I use this to get annotations on an image document on photoshop.
Running from ESTK it breaks on try/catch
function getAnnotationCount () { 
    var index = 0; 
    while (hideAnnotation (index)) { 
        index++; 
    return index; 
    function hideAnnotation (index) {
        var exists = true; 
        var desc = new ActionDescriptor (); 
        var ref = new ActionReference (); 
        ref.putIndex (stringIDToTypeID ('annotation'), index); 
        desc.putReference (stringIDToTypeID ('target'), ref); 
        try { 
            executeAction (stringIDToTypeID ('hide'), desc, DialogModes.NO);  // the error here
        } catch (e) { exists = false; }     
        return (exists);
