-// Hack to determine current script...
-//
-// These initial attempts failed:
-// 1. get an EcmaError and look at e.getSourceName(): try {eval ("static in return")} catch(e) { ...
-// Won't work because NativeGlobal.java only does a put of "name" and "message", not a wrapped reflecting object.
-// Even if the EcmaError object had the sourceName set.
-//
-// 2. var e = Packages.org.mozilla.javascript.Context.getCurrentContext().reportError('');
-// Won't work because it goes directly to the errorReporter, not the return value.
-// We want context.interpreterSourceFile and context.interpreterLine, which are used in static Context.getSourcePositionFromStack
-// (set by Interpreter.java at interpretation time, if in interpreter mode).
-//
-// 3. var e = Packages.org.mozilla.javascript.Context.getCurrentContext().reportRuntimeError('');
-// This returns an object, but e.message still does not have source info.
-// In compiler mode, perhaps not set; in interpreter mode, perhaps not used by errorReporter?
-//
-// What we found works is to do basically the same hack as is done in getSourcePositionFromStack,
-// making a new java.lang.Exception() and then calling printStackTrace on a string stream.
-// We have to parse the string for the .js files (different from the java files).
-// This only works however in compiled mode (-opt 0 or higher).
-// In interpreter mode, entire stack is java.
-// When compiled, printStackTrace is like:
-// java.lang.Exception
-// at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
-// at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39)
-// at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27)
