The reproducer is constructed from 
hotspot/jtreg/gc/g1/humongousObjects/TestHumongousClassLoader.java.

So the source code for ClassLoaderGenerator.class is 
test/hotspot/jtreg/gc/g1/humongousObjects/ClassLoaderGenerator.java.

This bug can be easily reproduced on Our latest Loongson 3A3000/4000 
processors.

Thanks a lot.
