Ktlint: adding disabledRules=["experimental:argument-list-wrapping"] triggers IndexOutOfBoundsException

[phileo]

Steps to Reproduce

brew install ktlint
git clone https://github.com/ricknout/android-mdc-theming
cd app/src/main/java

then run the following from command line:
ktlint -F --experimental --android --verbose --debug --disabled_rules=final-newline,parameter-list-wrapping,argument-list-wrapping,no-wildcard-imports,max-line-length,experimental:package-name

[Tapchicoma]

I could not reproduce to get exactly IndexOutOfBoundsException, but I got another one:

@phileo is this actual exception you see on running KtLint?

[phileo]

@Tapchicoma I retried ktlint on that project, and you're right, it does not repro the IndexOutOfBoundsException

Attached is a Test Class that I crafted which will reproduce the IndexOutOfBoundsException if you run with the same command line parameters as described above. It appears the max-line-length parameter influences this crash, because if you shorten some of the lines, the crash goes away

TestClass.zip

[paul-dingemans]

I can reproduce the issue with the TestClass example. In this case the "-a" flag is important as the error is not thrown when running without that flag.

In case my .editorconfig has an indent_size not equal to 2 (this is de default indent used in the example) then lint results in following messages:

When running format the IndexOutOfBounds exception occurs as described in previous comment. I expect that the IndentationRule and the ArgumentListWrapping rule have conflicts about the correct way to indent lines.

This is confirmed by disabling the indent rule as well. No IndexOutOfBounds occurs in that situation.

If I run with indent rule enabled on my local machine with all unmerged branches regarding changes in the indentation rule, the IndexOutOfBounds also does not occur. But in that case the ArgumentListWrapping rules does report lint errors while running the format command:

Those messages need to be investigated further. I expect they are caused by having non consistent indentation logic in the IndentationRule and the ArgumentListWrappingRule.
