### What you expected to happen

If "dubbo.provider.export=false", then this "ExporterDeployListener.onModuleStarted" should not be called, right?

### Anything else

the project params:

dubbo.protocol.name=dubbo
dubbo.protocol.serialization=hessian2
dubbo.protocol.port=27001
dubbo.protocol.threads=220

dubbo.application.name=xxxx-dubbo-server-${spring.application.name}
dubbo.application.register-mode=instance
dubbo.application.metadata-service-protocol=dubbo
dubbo.application.protocol=dubbo

dubbo.provider.export=false
dubbo.provider.token=true

dubbo.registry.protocol=zookeeper
dubbo.registry.address=${zookeeper.address}
dubbo.registry.file=/root/.dubbo/${spring.application.name}
dubbo.registry.use-as-config-center=true
dubbo.registry.use-as-metadata-center=true

Start at ConfigurableMetadataServiceExporter.java line 78 and trace the call from ExporterDeployListener.onModuleStarted when dubbo.provider.export=false. Reproduce with the listed configuration and verify that startup no longer logs the IndexOutOfBoundsException while the application continues running.
