Bug#873211: lintian: does not warn about .class binaries

[Carnë Draug <carandraug+dev@gmail.com>]

Package: lintian
Version: 2.5.50.4
Severity: normal

Dear Maintainer,

While improving the packaging of a Debian package, I found that the
source release included .class files (pre compiled java files).  Those
.class files were also part of the upstream release.  These upstream
compiled files were also included in the binary release.

While running lintian, I saw no warning about their presence.  This
can be reproduced with the imagej package 1.51i+dfsg-2 or older.

Best Regards,
Carnë
