Roman Puchkovskiy a7bc535e12 Fix native image build for the cases when io.netty.util.NetUtil is initialized at run-time (#10799) ... Motivation: In #10630, field substitutions were introduced for NetUtil.LOCALHOST4, NetUtil.LOCALHOST6 and NetUtil.LOCALHOST fields. They were required to allow a native image be built with most of Netty (including NetUtil) initialized at build time. The substitutions created in #10630 only define getters, so the 3 fields can only be read in a native image. But when NetUtil is initialized at run-time (this is what happens in #10797), its static initialization block is executed, and this block writes to all 3 fields. As the substitutions do not provide any setters, field stores are not valid, and such builds fail. Modifications: - Add netty-testsuite-native-image-client-runtime-init Maven module that builds a native image deferring NetUtil class initialization till run-time; this module is used to demonstrate the problem and verify the problem is gone with the fix - Add no-op setters to substitutions for NetUtil.LOCALHOST4, NetUtil.LOCALHOST6 and NetUtil.LOCALHOST Result: A native image initializing NetUtil at run-time builds successfully.
