LPS-37609 Split ClassLoaderPoolTest test methods separating them by functionality
LPS-37610 Split DLFileEntryFinderTest test methods separating them by functionality
LPS-37610 Use static constants
LPS-37610 How come some were "with" and others "by" ? Make them all the same.
Revert "LPS-37610 Split DLFileEntryFinderTest" -> I'm ok with the idea, but not with how it was implemented. The previous case for ClassLoaderPoolTest, made it easier to read, but this one makes it harder. How do we do it for the other finder tests?

This reverts commit dce85d9123e2a6b724e55ac4ace8007c83a3f4d1.
