  "message": "Add a `java_toolchain` attribute to specify options to the `header_compiler_direct` tool (#375)\n\nPrimary motivation is to let users not using the Turbine graal native image silence protobuf sun.misc.Unsafe warnings from the direct header compiler\n\nturbine_direct (header_compiler_direct) bundles protobuf, whose UnsafeUtil calls terminally-deprecated sun.misc.Unsafe methods. On JDK 24+ (JEP 498) the JVM prints a warning for each such call during header compilation:\n\n  WARNING: A terminally deprecated method in sun.misc.Unsafe has been called\n  WARNING: sun.misc.Unsafe::arrayBaseOffset has been called by\n  com.google.protobuf.UnsafeUtil (.../java_tools/turbine_direct_binary_deploy.jar)\n\nUnlike the Turbine worker, header_compiler_direct does not receive turbine_jvm_opts, and --jvmopt does not reach header-compilation actions, so a toolchain currently has no way to silence these warnings for the direct header compiler. Add --sun-misc-unsafe-memory-access\u003dallow to header_compiler_direct_jvm_opts, gated on the runtime feature version since the flag is rejected on JDK \u003c\u003d 22.\n\nSee https://github.com/protocolbuffers/protobuf/issues/20760.\n\nFixes #374\n\nCloses #375\n\nCOPYBARA_INTEGRATE_REVIEW\u003dhttps://github.com/bazelbuild/rules_java/pull/375 from davido:turbine-direct-unsafe-memory-access da635b6bebb7ac660f19451469182f54adea884c\nPiperOrigin-RevId: 968352943\nChange-Id: I94d5bc5d564016ced3cc3b6e06330fad4d8451a7\n",
