I was trying to make common scene code that would run equally on JPCT and JPCT-AE (with a small platform-specific layer). One difference is the package of the Light class: com.threed.jpct.util for JPCT and com.threed.jpct for JPCT-AE. This will be an issue for a cross-platform source if imports are explicitly declared.

I am trying to understand the rationale: this seems to be the same Light object, but not clear why different packages between platforms. Moreover, the com.threed.jpct.util still exists in JPCT-AE.

For now the workaround is to move Light to the platform-specific area.
