Hi Team,

When we use @Provider annotation with a class like below, it throws NPE.

@Provider public class GeneralExceptionMapper implements ExceptionMapper { // Some implementation }

and the exception thrown is below,

org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.raml:jaxrs-to-raml-maven-plugin:2.0.1-SNAPSHOT:jaxrstoraml (default) on project primehome-nbi-api: Execution default of goal org.raml:jaxrs-to-raml-maven-plugin:2.0.1-SNAPSHOT:jaxrstoraml failed. at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:212) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:153) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:145) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:116) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:80) at org.apache.maven.lifecycle.internal.builder.singlethreaded.SingleThreadedBuilder.build(SingleThreadedBuilder.java:51) at org.apache.maven.lifecycle.internal.LifecycleStarter.execute(LifecycleStarter.java:128) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:307) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:193) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:106) at org.apache.maven.cli.MavenCli.execute(MavenCli.java:863) at org.apache.maven.cli.MavenCli.doMain(MavenCli.java:288) at org.apache.maven.cli.MavenCli.main(MavenCli.java:199) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.codehaus.plexus.classworlds.launcher.Launcher.launchEnhanced(Launcher.java:289) at org.codehaus.plexus.classworlds.launcher.Launcher.launch(Launcher.java:229) at org.codehaus.plexus.classworlds.launcher.Launcher.mainWithExitCode(Launcher.java:415) at org.codehaus.plexus.classworlds.launcher.Launcher.main(Launcher.java:356) Caused by: org.apache.maven.plugin.PluginExecutionException: Execution default of goal org.raml:jaxrs-to-raml-maven-plugin:2.0.1-SNAPSHOT:jaxrstoraml failed. at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:145) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:207) ... 20 more Caused by: java.lang.NullPointerException at com.google.common.base.Preconditions.checkNotNull(Preconditions.java:212) at com.google.common.base.Joiner.toString(Joiner.java:447) at com.google.common.base.Joiner.appendTo(Joiner.java:113) at com.google.common.base.Joiner.appendTo(Joiner.java:154) at com.google.common.base.Joiner.appendTo(Joiner.java:142) at org.raml.utilities.format.Joiner.join(Joiner.java:57) at org.raml.jaxrs.parser.analyzers.JerseyAnalyzer.analyze(JerseyAnalyzer.java:80) at org.raml.jaxrs.parser.JerseyJaxRsParser.parse(JerseyJaxRsParser.java:73) at org.raml.jaxrs.raml.core.OneStopShop.parseJaxRsAndOutputRaml(OneStopShop.java:75) at org.raml.jaxrs.plugin.JaxRsToRamlMojo.confinedExecute(JaxRsToRamlMojo.java:120) at org.raml.jaxrs.plugin.JaxRsToRamlMojo.execute(JaxRsToRamlMojo.java:77) at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:134) ... 21 more [ERROR]
