During layout, the text area doesn't know what its eventual width will
be, so it has no way to provide a useful preferred height. It's a problem
for any component for which the preferred size in one dimension
depends on the actual size in the other. This might be good enough to
solve your problem (replacement for pack()):

  pack();
  messageComponent.setSize(messageComponent.getPreferredSize());
  pack();

You could write your own word-wrapping label class from scratch,
but there is no way to solve the basic problem of height/width
dependence. A double pack(), at least, would still be required.
