Package: pdftk Version: 2.02-3 Severity: minor Dear Maintainer,
pdftk fails messily with a non-helpful NullPointerException when run on a directory by mistake. To reproduce, run e.g. "pdftk ." I obtain the following result: Unhandled Java Exception in main(): java.lang.NullPointerException at gnu.gcj.runtime.NameFinder.lookup(libgcj.so.15) at java.lang.Throwable.getStackTrace(libgcj.so.15) at java.lang.Throwable.stackTraceString(libgcj.so.15) at java.lang.Throwable.printStackTrace(libgcj.so.15) at java.lang.Throwable.printStackTrace(libgcj.so.15) I would expect an error to be displayed. For instance, when running the command "pdftk does_not_exist" where "does_not_exist" is a nonexistent file, the output is: Error: Unable to find file. Error: Failed to open PDF file: does_not_exist Done. Input errors, so no output created. The output when trying to open a directory should be similar. -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (650, 'testing'), (600, 'experimental'), (600, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.3.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages pdftk depends on: ii libc6 2.22-3 ii libgcc1 1:5.3.1-12 ii libgcj15 4.9.3-12 ii libstdc++6 5.3.1-12 pdftk recommends no packages.
