The eclipse package currently doesnt use the java alternative. It looks
into /etc/eclipse/java_home and checks for the first JDK to be
installed. This leads to java-gch-compat to be used in your case.
Unfortunately the version of GCJ in etch does not implement the JDWP
stuff needed for debugging.

What you can do is change to search order /etc/eclipse/java_home or
override it for your user by putting "JAVA_HOME=/usr/lib/j2sdk1.5-sun"
into ~/.eclipse/eclipserc. Another way is to just deinstall
java-gcj-compat package.
