OpenJDK isn’t mentioned once in the apps description, and it is GPL which means this entire application may have to be GPL (IANAL)

[kryptiskt]

OpenJDK has the classpath exception in its version of the GPL, which allows non-GPL code to link to it without triggering GPL requirements.

This is a common misconception. The Classpath exception only applies to the class library, not to Hotspot (the core of the JVM implementation). The class library is also more tightly integrated with Hotspot than it used to be.

And of course the Classpath exception does not waive the notification and other requirements for the OpenJDK libraries that are distributed under the Classpath exception.
