I tried to load Zebra Crossing Bar Code Library in Oracle 12c environment. Most of the class files are created and loaded but there are some that are skipped. What does this skipping mean? Does it mean that loadjava utility didn't process given class files at all or does it mean that it has loaded but not compiled?
