I'm developing a custom component on Ubuntu (12.10 and 13.10) using the latest jdk8 available, b132.
I found that when a stroke type is set on a shape (I tested circles and rectangles), the shape size is changed accordingly to the stroke type set but it is always drawn as if the StrokeType.CENTERED.
I'm going to attach two screenshots where it's pretty obvious the correct behaviour on Windows and the wrong behaviour on Ubuntu.
Also a test project is attached, run "mvn clean compile exec:java" on the two different operating systems to see the difference.
