I do not see what you are seeing, if I create a class
org.apache.bcel.classfile.ClassWithNullConstantPoolItem and run javap I get:
```
javap -v
target/test-classes/org/apache/bcel/classfile/ClassWithNullConstantPoolItem.class
Classfile
/C:/Users/ggregory/git/a/commons-bcel/target/test-classes/org/apache/bcel/classfile/ClassWithNullConstantPoolItem.class
