Local fix

Problem summary

• The problem is caused when disposing named-keyed fonts in CFF
  format. Such fonts do not have FDArray. However, JDK is
  accessing FDArray while disposing such fonts which resulted in
  SIGSEGV.
  

Problem conclusion

• Font disposing code of JDK has been corrected to prevent SIGSEGV
  while handle FDArray.
