Actually this is completely theoretic question. But it's interesting why java specification don't allow uppercase characters letters in package and cause write something like this:
com.mycompany.projname.core.remotefilesystemsynchronization.*
instead of
com.myCompanyName.projName.core.remoteFileSystemSynchronization.*
Directly from Oracle Docs
Package names are written in all lower case to avoid conflict with the names of classes or interfaces.
