nmap: package-installs-java-bytecode

[Lukas Schwaighofer]

Hi Hilko,

nmap-common includes two .java files, along with their .class files.
These class files are now flagged by the newly added lintian tag
package-installs-java-bytecode [1].

I believe nmap's use case is quite special:  The class files are used
by the NSE script "jdwp-inject" and intended to be executed remotely
(if the injection succeeds).  Therefore I think the fact that we are
shipping the class files (and not jar archives) by itself is fine.
However, if I read the java policy correctly, any .class files shipped
by upstream must be removed (even from the source package).  That gives
us two choices:
* not ship the class files at all; the included README explains how to
  create them
* build-depend on default-jdk and re-create the class files when
  building the package
  - we still need to override the lintian tag in that case and should
    probably also ask debian-java at lists.debian.org if they are fine
    with that as per java policy

What do you think?

Regards
Lukas
