I am writing a Java cloud synchronization application with .jni integration for cloud file system virtualization in Windows Explorer.
Now I want to implement icon overlays, for example owncloud, to see the state of the node as follows:

I found several solutions for C #. Is this also possible with Java, if you use the jni interface to access icon handlers.
Does anyone know an existing solution?
PS The last question for this is 4 years, so in the end a new solution for modern systems with java8 in combination with the native .dll appeared.
Thanks for any hint.
