(minor thread hijacking)
I've just uploaded a version of javahelper to experimental
(0.17.experimental1) which uses the class version to work out the
correct alternate depends. If you run 'jh_depends -j' after dh_install
it will inspect all your jar files and add the correct default-jre | ...
line to the substvars as ${java:Depends}. (there are other options for
more complex scenarios and it does other things too)
That version uses javap -verbose, which is rather slow, other
suggestions welcome. It uses the following table:
highest version in the package => depends line
50 => java-runtime6
49 => java-runtime6 | java-runtime5
48 => java-runtime6 | java-runtime5 | java-runtime2
<48 => java-runtime6 | java-runtime5 | java-runtime2 | java-runtime
Of course, this doesn't catch a program compiled at 49 which depends on
a library compiled at 50, since the library doesn't keep depends
information, but it's a good first start.
