`Modules.enter` completes all root modules, but in case of additional modules being added to the module graph via `Modules.addExtraAddModules` (either from javadoc, or using the `CompilationTask.addModules`, these extra modules may not be completed at this time. Normally, they are completed eventually, but if their `module-info`s contain `import module`, an NPE will appear while checking the import, before the complete happens.
The proposal herein is to consistently complete all modules in the module graph when the module graphs is setup. ------------- Commit messages: - Adding javac test. - Cleanup. - 8370334: javadoc NPE with "import module" statement Changes: https://git.openjdk.org/jdk/pull/27974/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=27974&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8370334 Stats: 73 lines in 3 files changed: 68 ins; 0 del; 5 mod Patch: https://git.openjdk.org/jdk/pull/27974.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/27974/head:pull/27974 PR: https://git.openjdk.org/jdk/pull/27974
