-/**
- * Transforms Eclipse's <code>org.eclipse.jdt.core.dom.ASTConverter</code> class, which sometimes rescans bits and pieces
- * of source files because Eclipse's own AST doesn't actually have enough information for eclipse (why they don't just fix
- * the AST tree generator is beyond me). At any rate, for catch blocks generated by lombok, eclipse tries to rescan the
- * source file to find the source position of the catch statement, which will of course fail as there's nothing there.
- * We will fix the code to return the original starting position, which is a pretty good simile, instead of '-1', which
- * screws up all sorts of things.
- *
- * Transformations applied:<ul>
- * <li>The <code>retrieveStartingCatchPosition(int, int)</code> method is instrumented to return its first parameter
- * instead of the constant -1.</li></ul>
