Jasper reports defines a dependency to olap4j which is version 0.9.7.309-JS-3,
this version defines a SqlDriver implementation namely org.olap4j.driver.xmla.XmlaOlap4jDriver
which is not valid i.e. it doesn't define a public constructor. This causes the DriverManager
to fail its registration of drivers.
A newer version of olap4j fixes this issue, it was released in Mar 23, 2016 so its there
for a while already, can you update the dependency to the 1.2.0.
