I am having a Problem with Jasper Reports PDF generation in my Java Spring App.
Versions:
Jasper Files built with the jasperreports-gradle-plugin version 0.3.2
<!-- Created with Jaspersoft Studio version 6.11.0.final using JasperReports Library version 6.11.0-0c4056ccaa4d25a5a8c45672d2f764ea3498bebb -->

When I comment out the above code snippet from my jrxml file it works for all examples I have setup. However when I add this back it works for all except for one, in which case it gives the following stack trace:
SEVERE: Servlet.service() for servlet [orderInvoice] in context with path [/orderInvoice] threw exception [Request processing failed; nested exception is java.lang.IndexOutOfBoundsException: Index: 0, Size: 0] with root cause
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

This does not make sense as something that should happen sometimes, and not all the time. The string that is passed in is hard coded in the code as a way to manage any updates, but this feels more like a configuration issue over a jrxml issue given this bit of code has been stable for over a year, and does not act up in normal changes. I have unified the JasperReport library used to build the jrxml's. I checked each version to try to figure out what is wrong, and could use either a fix or ideas for how to find a fix. I have not found anything on google or any obvious issues.
Thanks
So this was a product of some cleanup I performed on the app in question.
The original designed included some tagging to make the PDF ADA compliant since it used an old version of Jasper Reports. I removed this to resolve some stability issues, but had a new set of stability issues (see question).
The issue was with this bit of code:
SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration();
configuration.setTagged(true);
This true is needed to support these added tags, but with them removed this is causing trouble, so this becomes:
SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration();
configuration.setTagged(false);
