14 Perhaps it should. On the other hand you don't have to, it will be set
15 automatically during the vm update process (which is described).
16 java-config-2 -s is only mentioned because it differers from the plain
17 portage case.

20 >> 1. If I do java-config-2 -S sun-jdk-1.4, ant-core continues to build

22 Because system vm has nothing to do with emerge. For that you set the
23 build jdk. Note that system vm can be a jre or a jdk, while compilation
24 jdk has to be a jdk. This procedure differs from a plain portage
25 installation, and should perhaps be mentioned somewhere.
26
27 >> 2. Junit does not compile even having compiled ant-core with 1.4 vm
28 >> (I had to modify jdk.conf)
29 The the default jdk.conf will not make 1.4 sources build with a 1.5 jdk,
30 so you do not *have* to modify jdk.conf. However, you *must not* changee
31 jdk.conf to an invalid state, which is currently possible (and you must
32 have done). Perhaps there should be a warning in the sample file?
33 (something like "# Warning: Do NOT set a 1.5 jdk for use with anything
34 but 1.5 sources!")
35 If Junit doesn't compile after having (re-)emerged all java-packages
36 with a corrected jdk.conf, file a bugreport. To find all packages you
37 have to re-emerge use java-1.5-fixer from the list.
