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.
