solaris-sparc/bin/java -version
java version "1.4.1-rc"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-rc-b18)
Java HotSpot(TM) Client VM (build 1.4.1-rc-b18, mixed mode)

Here attached is a test case to reproduce the problem.
Run the TreeDemo testcase with following steps.
a. Select root "Books for Java Implementers" in the EditorPane
b. Select node "The Java Virtual Machine Specification"
c. You would see "Modifying a DWDM Connection" page
d. Scroll the page down to see "Detach a Connection"
e. Notice that the Step-Task table alingment is improper
   For 1, 2 and 3 the left indentation is different and are not aligned
  in with same left margin.
 
If you play around with the other links and come back to this page
some times you see the correct alignment.
For verification , one can view the page (vm.html) in a browser and
see the alingment difference.

I used terms alingment , left margin, and left indentation all meaning the same
