    /*
 * Problem: Same declarationNode can be the subject of multiple calls to this method.
 * For the 2nd++ calls, the original declarationNode has already been rewritten, and this has to be taken into account.
 * 
 * Assumption:
 * - Modifiers for each VariableDeclarationFragment are modified at most once.
 * 
 * Solution:
 * - Maintain a map from original VariableDeclarationFragments to their new FieldDeclaration.
 * - Original modifiers in declarationNode belong to the first fragment.
 * - When a later fragment needs different modifiers, we create a new FieldDeclaration and move all successive fragments into that declaration
 * - When a fragment has been moved to a new declaration, make sure we don't create a new move target again, but instead use the already created one
