Rawtypes: In JRuby 9.2, `RubyArray` is a generic, so references throughout our codebase to the now "raw" type trigger warnings. In most cases we cannot actually resolve the issue, since the JRuby-provided methods for creating `RubyArray`s still return the raw type, so these have been suppressed. 2. Deprecations: - `RubyString#intern19()` -> `RubyString#intern()` - `RubyString#downcase19(ThreadContext)` -> `RubyString#downcase(ThreadContext)` - `NativeException`: remove import & reference directly; suppress usage warnings - `RaiseException()`: migrate to equivalent non-deprecated methods wherever possible; in some cases where we are using this in conjunction with the also-deprecated `NativeException` to preserve java stacktraces, there seems to be no non-deprecated path forward, so these cases have been suppressed. 3. Redundant Casts - Resolved * JRuby 9.2 bundler shenanigans (elastic#10266) * Revert "Revert "remove forced dependency on old bundler (elastic#9395)"" This reverts commit bef9841. * plugin management: update internal bundler to 1.17.x APIs * deps: update dev dependency webmock to version compatible with JRuby 9.2 * spec: update Pack fixture to include manticore version that doesn't conflict * build: update gradle to version that has Java 11 support * java11: resolve or suppress deprecation warnings * Remove superfluous flag opting into ParNew GC implementation When opting into CMS garbage collector with `XX:+UseConcMarkSweepGC`, the young generation collector ParNew has been the default since Java 8, making the `XX:+UseParNew` flag redundant; the flag was removed in Java 9, and should no longer be specified to work with modern Javas. https://bugs.openjdk.java.net/browse/JDK-8006478 https://openjdk.java.net/jeps/214 * spec: set thread name to example description for easier debugging * spec: prevent errors in testing specs by checking against skip list before using * no-op: remove use of `HashMap#computeIfAbsent` on single-threaded code > This method will, on a best-effort basis, throw a `ConcurrentModificationException` > if it is detected that the mapping function modifies this map during computation. > > -- https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/util/HashMap.html#computeIfAbsent(K,java.util.function.Function) * qa: by default, run integration against Elastic Stack 6.5.x To support development on Logstash on top of Java 11, default to testing against an Elastic Stack that is capable of running on Java 11. * qa: ignore deprecation warnings when comparing offline pack output * qa: add Java 9+ support to ChildProcess dev dependency this can safely be removed when the childprocess gem supports Java9+ enkessler/childprocess#141 * qa: allow connections to localhost in webmock * bump jrjackson version * fix filebeat integration tests * spec: ensure license compliance spec runs first The license compliance spec that validates the licenses of bundled plugins appears to not be compatible with the hooks that we inject into bundler for plugin management, and will fail in obscure ways when run after those hooks have been added. Since those hooks are not necessary for validating licenses, the easiest solution was to ensure that those specs run first, before the VM has been poluted. Since the gradle/junit/rspec bridge that is currently in place runs all specs in the same JVM, we also need to make sure that the rspec "world" is reset before a run, to ensure that it doesn't retain spec definitions from previous runs. Also updates the rake invocation, although I'm not sure it is used any more.
