This extension depends on the JPMML-Evaluator library version 1.1.16, which is ~2.5 year old (released in February 2015). It's two development cycles (1.2.X and 1.3.X) behind the current version, and as such doesn't benefit from any improvements and optimizations that have been implemented over the time.

Also, please note that JPMML-Evaluator 1.1.0 and newer are released under Affero GPLv3, which means that the license grant of this extension is invalid.

Need to have support for XGBoost algorithm with Siddhi PMML extension.

Bullet 4 of the Read Me File under the 'How to Use section' states, "You can use this extension after copying the component jar to the <STREAM_PROCESSOR_HOME>/lib directory." None of the files associated with hyperlink on the word jar has an actual jar file.

I downloaded the file for version 4.0.0 but it didn't fix the error.
