Local fix

Problem summary

• Problem is caused when a package ID becomes visible in the
  classloader hash table before the class defining it has been
  added to the table.
  

Problem conclusion

• Ensure that both the package ID and the class defining it are in
  the classloader hash table, or that neither are.
