Missing dependencies makes you think pdftk is not working

[Nicolas Marchildon]

Binary package hint: pdftk

After installing pdftk, I invoked it and got two warnings:

WARNING: Error loading security provider org.bouncycastle.jce.provider.BouncyCastleProvider: java.lang.ClassNotFoundException: org.bouncycastle.jce.provider.BouncyCastleProvider not found in gnu.gcj.runtime.SystemClassLoader{urls=[file:./], parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}
WARNING: Error loading security provider gnu.crypto.jce.GnuCrypto: java.lang.ClassNotFoundException: gnu.crypto.jce.GnuCrypto not found in gnu.gcj.runtime.SystemClassLoader{urls=[file:./], parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}

After installing these two packages it stopped complaining:

sudo apt-get install libgnucrypto-java libbcprov-java

apt-cache show pdftk shows:

Version: 1.41-2
Depends: libc6 (>= 2.6.1-1), libgcc1 (>= 1:4.2.1), libgcj8-1 (>= 4.2.1), libstdc++6 (>= 4.2.1)
Suggests: xpdf-utils

Perhaps it should also suggest the two packages mentioned above.
