Enum classes with abstract methods don't compile ------------------------------------------------ Key: IPROTO-132 URL: https://issues.redhat.com/browse/IPROTO-132 Project: Infinispan ProtoStream Issue Type: Bug Affects Versions: 4.3.2.Final Reporter: Ryan Emerson Priority: Major Fix For: 4.3.3.Final {{ProtoMessageTypeMetadata}} checks fail when an Enum implementation relies on the enum instances implementing one or more abstract methods. For example, the {{org.infinispan.commands.write.ValueMatcher}} class. {code:java} org.infinispan.protostream.annotations.ProtoSchemaBuilderException: The type org.infinispan.commands.write.ValueMatcher of field 'valueMatcher' of org.infinispan.commands.write.ReplaceCommand should not be abstract. at org.infinispan.protostream.annotations.impl.ProtoMessageTypeMetadata.discoverFields(ProtoMessageTypeMetadata.java:343) at org.infinispan.protostream.annotations.impl.ProtoMessageTypeMetadata.scanMemberAnnotations(ProtoMessageTypeMetadata.java:178) at org.infinispan.protostream.annotations.impl.BaseProtoSchemaGenerator.generateAndRegister(BaseProtoSchemaGenerator.java:116) at org.infinispan.protostream.annotations.impl.processor.AutoProtoSchemaBuilderAnnotationProcessor.processClass(AutoProtoSchemaBuilderAnnotationProcessor.java:320) at org.infinispan.protostream.annotations.impl.processor.AutoProtoSchemaBuilderAnnotationProcessor.processElement(AutoProtoSchemaBuilderAnnotationProcessor.java:251) at org.infinispan.protostream.annotations.impl.processor.AutoProtoSchemaBuilderAnnotationProcessor.processDependencies(AutoProtoSchemaBuilderAnnotationProcessor.java:380) at org.infinispan.protostream.annotations.impl.processor.AutoProtoSchemaBuilderAnnotationProcessor.processClass(AutoProtoSchemaBuilderAnnotationProcessor.java:312) at org.infinispan.protostream.annotations.impl.processor.AutoProtoSchemaBuilderAnnotationProcessor.processElement(AutoProtoSchemaBuilderAnnotationProcessor.java:251) at org.infinispan.protostream.annotations.impl.processor.AutoProtoSchemaBuilderAnnotationProcessor.process(AutoProtoSchemaBuilderAnnotationProcessor.java:178) at jdk.compiler/com.sun.tools.javac.processing.JavacProcessingEnvironment.callProcessor(JavacProcessingEnvironment.java:980) at jdk.compiler/com.sun.tools.javac.processing.JavacProcessingEnvironment.discoverAndRunProcs(JavacProcessingEnvironment.java:896) at jdk.compiler/com.sun.tools.javac.processing.JavacProcessingEnvironment$Round.run(JavacProcessingEnvironment.java:1222) at jdk.compiler/com.sun.tools.javac.processing.JavacProcessingEnvironment.doProcessing(JavacProcessingEnvironment.java:1334) at jdk.compiler/com.sun.tools.javac.main.JavaCompiler.processAnnotations(JavaCompiler.java:1258) at jdk.compiler/com.sun.tools.javac.main.JavaCompiler.compile(JavaCompiler.java:936) at jdk.compiler/com.sun.tools.javac.api.JavacTaskImpl.lambda$doCall$0(JavacTaskImpl.java:104) at jdk.compiler/com.sun.tools.javac.api.JavacTaskImpl.handleExceptions(JavacTaskImpl.java:147) at jdk.compiler/com.sun.tools.javac.api.JavacTaskImpl.doCall(JavacTaskImpl.java:100) at jdk.compiler/com.sun.tools.javac.api.JavacTaskImpl.call(JavacTaskImpl.java:94) at org.codehaus.plexus.compiler.javac.JavaxToolsCompiler.compileInProcess(JavaxToolsCompiler.java:126) at org.codehaus.plexus.compiler.javac.JavacCompiler.performCompile(JavacCompiler.java:174) at org.apache.maven.plugin.compiler.AbstractCompilerMojo.execute(AbstractCompilerMojo.java:1134) at org.apache.maven.plugin.compiler.TestCompilerMojo.execute(TestCompilerMojo.java:180) at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:137) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:210) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:156) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:148) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:117) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:81) at org.apache.maven.lifecycle.internal.builder.singlethreaded.SingleThreadedBuilder.build(SingleThreadedBuilder.java:56) at org.apache.maven.lifecycle.internal.LifecycleStarter.execute(LifecycleStarter.java:128) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:305) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:192) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:105) at org.apache.maven.cli.MavenCli.execute(MavenCli.java:956) at org.apache.maven.cli.MavenCli.doMain(MavenCli.java:288) at org.apache.maven.cli.MavenCli.main(MavenCli.java:192) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.codehaus.plexus.classworlds.launcher.Launcher.launchEnhanced(Launcher.java:282) at org.codehaus.plexus.classworlds.launcher.Launcher.launch(Launcher.java:225) at org.codehaus.plexus.classworlds.launcher.Launcher.mainWithExitCode(Launcher.java:406) at org.codehaus.plexus.classworlds.launcher.Launcher.main(Launcher.java:347) {code}
