JDK-8259726: Use of HashSet leads to undefined order in test output #2086

wants to merge 2 commits into from


Copy link

@jonathan-gibbons jonathan-gibbons commented Jan 14, 2021

Small cleanup in code, changing HashSet to ArrayList, with a corresponding beneficial impact on tests.

The irony is that this was originally done with the intent to change the element type from String to HtmlId, but having tried that, it seems better to localize the conversion from ids to class names, so I just cleaned up the expository comment a bit.

I rewrapped some of the long text block lines as well.
