ArrayIndexOutOfBoundsException with xml.format.grammarAwareFormatting set to true

[enxio]

Hi,

I am getting the exception below when trying to format with xml.format.grammarAwareFormatting being set to true. With the setting being false, no exception occurs. Afterwards, formatting (sometimes) behaves erratic, I was not able to further track this down. It might be related.

Please let me know how I can help to track this further down.

Thanks for any clarification.

Please share your xml file that you are tring to format.

Unfortunately, I can't. It's full of proprietary information.

I see whether I can track this further down and come up with a demonstrator.
