ArrayIndexOutOfBoundsException errors

[cybersonic]

I am getting loads of the following error (with different indexes of course) in a scan of a client's source code:

Error: "java.lang.ArrayIndexOutOfBoundsException" Location: com.cflint.CFLint.process(CFLint.java:346)
com.cflint.exception.CFLintScanException: java.lang.ArrayIndexOutOfBoundsException

	at com.cflint.cli.CFLintCLI.main(CFLintCLI.java:339)
Caused by: java.lang.ArrayIndexOutOfBoundsException

What would be a good way to debug this error to be able to provide better information?

The command I am running is java -jar ~/bin/CFLint-1.4.0-all.jar -folder .

If you want to debug yourself, fire up com.cflint.cli.CFLintCLI in an IDE (Eclipse).

Or if you want help here, could you please give the next couple lines, the real cause at the lines shown after "Caused by: java.lang.ArrayIndexOutOfBoundsException".

I am seeing the same issue as Mark:

... 9 more

I may debug the problem this weekend.

Getting a similar error in a differe.nt location. Maybe a separate bug, but noting it here.

I get this too on Win10 w/ JRE 8u181. But it still produces a cflint-result.html with plenty of results. I'm guessing there's a file somewhere in there that it doesn't know how to parse. I'll check into it more on Linux tonight.

It looks like sometimes the attempt to determine the column is generating an outofbounds (and not reporting that error). Wrapping the setColumn calculation with a try/catch.

fixed in dev branch.
