java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)

1. Creating a JTextArea object and putting it inside a JScrollPane
2. Showing the JScrollPane as the Object passed to JOptionPane.showMessageDialog
3. Initially the text is scrolled to the bottom not the top

Only happens with JRE 1.3 not JRE 1.2.2, and only when used by an applet using
the plugin. Works when used by an application run using JRE 1.3.

  private static String DECLARATION = "When in the Course of human events it bec
omes necessary for one people to dissolve the political bands which have connect
ed them with another, and to assume among the powers of the earth, the separate
and equal station to which the Laws of Nature and of Nature's God entitle them,
a decent respect to the opinions of mankind requires that they should declare th
e causes which impel them to the separation.\n\nWe hold these truths to be self-
evident, that all men are created equal, that they are endowed by their Creator
with certain unalienable Rights, that among these are Life, Liberty and the purs
uit of Happiness. That to secure these rights, Governments are instituted among
Men, deriving their just powers from the consent of the governed. That whenever
any Form of Government becomes destructive of these ends, it is the Right of the
 People to alter or to abolish it, and to institute new Government, laying its f
oundation on such principles and organizing its powers in such form, as to them
shall seem most likely to effect their Safety and Happiness. Prudence, indeed, w
ill dictate that Governments long established should not be changed for light an
d transient causes; and accordingly all experience hath shewn that mankind are m
ore disposed to suffer, while evils are sufferable, than to right themselves by
abolishing the forms to which they are accustomed. But when a long train of abus
es and usurpations, pursuing invariably the same Object evinces a design to redu
ce them under absolute Despotism, it is their right, it is their duty, to throw
off such Government, and to provide new Guards for their future security. Such h
as been the patient sufferance of these Colonies; and such is now the necessity
which constrains them to alter their former Systems of Government. The history o
f the present King of Great Britain is a history of repeated injuries and usurpa
tions, all having in direct object the establishment of an absolute Tyranny over
 these States. To prove this, let Facts be submitted to a candid world.";
