[jdk17u-dev] RFR: 8225377: type annotations are not visible to javac plugins across compilation boundaries

Tue Oct 28 12:03:55 UTC 2025

[JDK-8341779](https://bugs.openjdk.org/browse/JDK-8341779) is a redo of the backport of [JDK-8323093](https://bugs.openjdk.org/browse/JDK-8323093), see also discussion in CSR [JDK-8346471](https://bugs.openjdk.org/browse/JDK-8346471).

JDK-8341779 was backported to JDK 21u and released in 21.0.8, as discussed in the CSR this PR proposes integrating it into a future 17u release now that 21.0.8 has been released.

Similar to [JDK-8360406](https://bugs.openjdk.org/browse/JDK-8360406) for 21u, a future backport will disable this logic for 17u by default, and optionally allow the fix to be enabled with `-XDaddTypeAnnotationsToSymbol`.
