[Subclipse-dev] Question for the co-existence of library source code

Hello,

I am a student at TU Delft, Netherlands. I am currently working on my thesis project and I am performing an empirical study regarding software quality.

I was looking into the source of subclipse and its evolution. At some point (I was checking the difference between release 1.2.1 and 1.4.0 ) , the modules:

org.tigris.subversion.clientadapter.javahl
org.tigris.subversion.clientadapter.svnkit
SvnClientAdapter

they co-exist increasing the volume and the duplication of the system.

Of course, I understand these are probably imported libraries. However, they are imported as source code.

My question is whether these library source files were imported so that they can be modified? In other words, do you put maintenance effort on that source code or is it just imported libraries?

I would appreciate it if you would answer me. Thank you in advance for your time and consideration.

Kind regards,
