Hi Ben,
trying to understand this one better. It seems that LCMS is a color

and that seems to alter the way the JVM works with color profiles?

Here is the relevant part of the stack trace:

PS: first time I hear of this package, care to venture a guess on how
common it is to have
this one installed?
