<Swing Dev> RFR: 8160720: [TEST_BUG] javax/swing/SwingUtilities/TestBadBreak/TestBadBreak.java

[Prasanta Sadhukhan]

Test hardcodes bufferedimage and frame bounds so it does not capture correct size if scaling factor is used.
The solution is to always use the same uiscale=1, an updated test still can reproduce the JDK-8015085 issue without fix. Additionally, moved the frame to centre of screen for better mach5 stability.
Mach5 job running for several iterations on all platforms is ok. Link in JBS.
