Because in the packages that are being prepared currently this reads:

Build-depends: kaffe
Depends: kaffe | java2-runtime

So a user who does either 'apt-get source eclipse' or 'apt-get install
eclipse' will link (either at compilation time or at runtime) to Kaffe's
Java library, and to Kaffe JVM bindings which are all GPL.

In principle you're right.

Yet, if you *package* this program together with a JVM, so that when
the user says "I want to build this package" or "I want to run this
package" the user gets your program with a specific JVM, then it's not
a mere aggregation, but these two are explicitely bound together.

And GPL also says, that the person who packages and then distributes
breaks the rules of GPL, it has no longer right to distribute nor use
the GPLed work.  And we do want to be able to distribute Kaffe, for
it's very good for all GPL-compatible programs on platforms it supports.
