Apache POI XMLHelper Error: 'accessExternalStylesheet' Feature Unsupported - Troubleshooting Guide

This error message indicates that the SAX feature requested by the code using the Apache POI library is not supported by the Java Virtual Machine (JVM) that is running the code. The specific feature in question is 'accessExternalStylesheet', which is used to control the ability of an XML parser to access external stylesheets.

The error message also suggests that the code is suppressing logging output related to this issue for the next five minutes. This is likely intended to prevent excessive logging output from overwhelming the application's logs.

To resolve this issue, you may need to update your JVM to a newer version that supports the requested SAX feature, or modify your code to avoid using that feature. Alternatively, you may be able to configure your JVM to enable the unsupported feature, although this may not be advisable due to security concerns.
