@Override
public boolean enterThrowNode(final ThrowNode throwNode) {
lineNumber(throwNode);
if (throwNode.isSyntheticRethrow()) {
//do not wrap whatever this is in an ecma exception, just rethrow it
load(throwNode.getExpression());
method.athrow();
return false;

// NOTE: we first evaluate the expression, and only after it was evaluated do we create the new ECMAException
// object and then somewhat cumbersomely move it beneath the evaluated expression on the stack. The reason for
// this is that if expression is optimistic (or contains an optimistic subexpression), we'd potentially access
// the not-yet-<init>ialized object on the stack from the UnwarrantedOptimismException handler, and bytecode
// verifier forbids that.
