Thank you for the tip.

1) the trace shows:

2) that the proper /usr/lib/ is in fact loaded before

3) however, the loading starts from

which is an eclipse default library bundled with the eclipse
application, and which is compiled against foreign

lddtree /home/work/space/none-4.5.0/conf/org.eclipse.osgi/748/0/.cp/ => /home/work/space/none-4.5.0/conf/org.eclipse.osgi/748/0/.cp/ (interpreter => none) => not found

4) the library  loading logic of eclipse is: first try to load bundled
libraries from private paths,
and if that fails, then try to load these libraries from the public
paths, such as "/usr/lib/*", etc.

5) I do provide replacement libswt-* libraries built against musl on the
public path "/usr/lib/*",
and the assumption was that when private path library loading fails,
then the library will be loaded from the public path, which "sort of
almost works",
* was that a wrong assumption? 
* will in fact musl reject libraries linked to the
* if not, is there a way to tell musl to blacklist private path
