[armedbear-devel] "Inconsistent precedence graph" when calling print-object on java instance

[Alan Ruttenberg]

Didn't seem to do it:

(ensure-java-class (find-java-class
"uk.ac.manchester.cs.owl.owlapi.OWLClassImpl"))

Fails - trackback below.

Could it have something to do with the different classloaders? I'm
using the bsh class loader.
