Srategy

A first C++ wrapper is taking care of the creation of a Java Virtual Machine(JVM) as well as loading the Tika Java library via JNI.

It is then encapsulated in a DLL which is dynamically loaded by UE4 and called from a blueprint library.

Warning

Since the plugin is using a Java virtual machine, you will see memory exceptions if you are using Visual Studio. You can just skip them.
