Hi Alan,

Do you have a test to reproduce the issue or can you describe the steps to reveal it?

I have a Swing program that works fine on JDK 8 but runs like a dog [unusably

FlowView.layout), which is a whopping 20–25 times slower on JDK 9.

Any idea what might have changed to cause this slowdown?

Could it be the result of the new String implementation?
