  7578 java     NAMI  "/proc/curproc/file"
  7578 java     RET   readlink 7
  7578 java     CALL  write(0x2,0x8051870,0x21)
  7578 java     GIO   fd 2 wrote 33 bytes
       "Error: could not find libjava.so
       "
  7578 java     RET   write 33/0x21
  7578 java     CALL  write(0x2,0x8051894,0x32)
