That's correct.  I'm trying to understand if there was a specific reason for caching of compiled packages / compilation units to be removed.  It might have made the build faster or some other reason.

Here is the changelog from about the time of R4.9 (2018-09-05):  https://git.eclipse.org/c/jdt/eclipse.jdt.core.git/log/?ofs=1950  But as I look back between R4_9 and R4_7_3a it is hard to tell from the descriptions if any refer to closing open handles or disabling caching of model data.
