Illegal reflection access denial in which future release

[S A]

Hi all,

TL;DR is a future JDK release known, when illegal reflection access is no
longer possible? If not, are there estimations / discussions / FAQs /
documentation?

The product I work on (Eclipse+xtext IDE + backend) has nearly completed
the move to OpenJDK 11 (from OpenJDK 8) and we are working on supposedly
not pressing issues. One of those issues is illegal access via reflection.

We would obviously like to be prepared and so are estimating effort and
time constraints of fixing illegal reflection access. As this includes
multiple libraries, knowing *when* we need to finish our efforts is quite
important.

Sorry if this has been asked before (I imagine yes), but searching for the
topic yields lots of how to work around or fix the issue. Thank you in
advance.

Best regards,
Simeon
