After this change, pdfsam starts for me and shows me an empty white
window (or grey-ish) with nothing in it.


On the console I see:

% pdfsam
[warning] /usr/bin/pdfsam: No java runtime was found
=========================================================================

(Note the phoning home "feature" at the bottom.)

So there is still a (spurious?) warning at the top, and I have no
idea what I could do with the empty window :)

[The warning indeed disappears with
`JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 pdfsam'.]


Another try with the companion binary:

% pdfsam-console -h
[warning] /usr/bin/pdfsam-console: No java runtime was found

                                      encrypt, slideshow, decrypt.

Usage: java -jar pdfsam-console-2.0.6e.jar [options] command

where:

command = command to execute {[concat], [split], [encrypt], [mix], [unpack],
          [setviewer], [slideshow], [decrypt]} (required)

and options are:

-?        prints usage to stdout; exits (optional)
-h        prints usage to stdout; exits (optional)
-help     displays verbose help information (optional)
-license  displays license information (optional)
-version  displays command's version (optional)

Option tags are not case sensitive, and may be truncated as long as they remain
unambiguous.  Option tags must be separated from their corresponding values by
whitespace, or by an equal sign.  Boolean options (options that require no
associated value) may be specified alone (=true), or as 'tag=value' where value
is 'true' or 'false'.


And now it gets weird: I tried `DEBUG_WRAPPER=1 pdfsam' several
times, and at more or less each second invocation, I get java
exceptions:

% DEBUG_WRAPPER=1 pdfsam

Ok, same without DEBUG_WRAPPER; every second or third call to pdfsam
ends with this exception.

Somethings phishy here -- and I'm sorry but I have no clue what else
to try ...


Cheers,
gregor
