As of version 7.4.3.25-ga25 and up (I didn't checked older versions)
the implementation of "isCheckedOut" method in DLFileEntryImpl.java uses: DLFileEntryServiceUtil.isFileEntryCheckedOut
This means it will check the permissions - that is not desirable I
think on that low level.
Shouldn't be
used: DLFileEntryLocalServiceUtil.isFileEntryCheckedOut
to skip premission checking ?
for example hasLock() or getContentStream(String version) methods in
the same class "DLFileEntryImpl.java " use "DLFileEntryLocalServiceUtil".
