I'm having issues with IntelliJ automatic Reformat Code on one specific line of code:

catch (MyException1 | MyException2 | MyException3 | MyException4 | MyException5 | MyException6 | MyException7 | MyException8 e) {

• I have set in Editor -> Code Style Hard wrap at 140
• In Editor -> Code Style -> Java -> Wrapping and Braces everything is either Chop down if Long or Wrap if long

Now, the issue is that running Code -> Reformat Code doesn't break this line into 2 automatically (it should as it exceeds 140 characters). And what's worse, if I break it manually, then Reformat Code will bring it back to one line. As I have the Line Length inspection on, IntelliJ complains about this line.

This is the only line in the whole project where IntelliJ has this problem, all other expressions containing or || etc. are correctly wrapped.

Wrapping or chopping down multi-catch types is not supported on IntelliJ IDEA 2021.3 and below. IntelliJ IDEA 2022.1 will support this. See https://youtrack.jetbrains.com/issue/IDEA-178941
