Brodie:

Everything the JVM does eventually ends up using system libraries, some directly, some indirectly. The JVM is really a native application that interprets byte codes (Java binaries) and translates them into the native language of the machine for execution.

That said, the fact that this problem "disappeared" after you did a complete OS re-install kind of implies to me that your JVM was referencing an outdated library that was probably held onto during an upgrade. This is a guess, by the way.

This sort of thing isn't supposed to happen but it does.

Best wishes,

Bill Wagner

Apart from source code, what are all the factors affecting AWT rendering?  I
had an app working under 10.3.9 with JRE 1.4.2_07.  It had a clipping bug under
10.4.9 with both JRE 1.4.2_09 and JRE 1.5.0_06.  I upgraded and reformatted my
disks (for other reasons), and now the bug does not appear under any OS
version.  The source code has not changed, though, so it's still lurking
somewhere.  I have checked all combinations of

* OS versions 10.3.9 and from 10.4.6 to 10.4.10
* Java updates recommended by Software Update (various JREs and VMs)
* Java System Properties like apple.awt.antialiasing (I don't set any)

The bug never appeared in XP or 10.3.9, but had been very consistent under
10.4.9.  Does the version of QuickTime or any system-wide preferences affect
AWT rendering?
