After upgrading POI from 3.9 to 3.15 we were getting a:

javax.xml.stream.FactoryConfigurationError: Provider for class javax.xml.stream.XMLEventFactory cannot be created

Besides POI, our build included:

compile ('com.msopentech.odatajclient:odatajclient-engine:0.9.0')

it turned out that the odatajclient jar included a java.xml.stream.XMLEventFactory file in its META-INF\services, the contain of that file was com.fasterxml.aalto.stax.EventFactoryImpl but the aalto included in odatajclient was old and com.fasterxml.aalto.stax.EventFactoryImpl was finally inheriting from com.msopentech.javax.xml.stream.XMLEventFactory instead of java.xml.stream.XMLEventFactory class.

At run time POI was using the java.xml.stream.XMLEventFactory, the class loader returned com.fasterxml.aalto.stax.EventFactoryImpl and the cast to java.xml.stream.XMLEventFactory failed.

The solution was excluding the module that included the old aalto:

compile ('com.msopentech.odatajclient:odatajclient-engine:0.9.0')
{
   exclude group: 'com.msopentech.odatajclient', module: 'odatajclient-engine-xml'
}
