In addition to what Dan Dyer said:

  • calling executables by a fixed path or of a fixed name
  • assuming a certain shell command syntax will work properly (eg 2>&1 or something)
  • deleting or renaming a file that some other process (or the same one!) might have open
  • Making assumptions about the working directory (eg using relative paths to load resouces from the file system)

  • Hard-coding file separators/paths.
  • Using native libraries.
  • Using Runtime.exec()
  • Using sun.* classes (this may cause portability issues with non-Sun JVMs).
