This bug happens in `KafkaProducerManager::prepare` method, which is a `BootService`. It works in the same thread with `SkyWalkingAgent::premain`. ``` AdminClient adminClient = AdminClient.create(properties); ``` Just see the Thread dump. ``` init:278, LoginContext (javax.security.auth.login) <init>:512, LoginContext (javax.security.auth.login) login:59, AbstractLogin (org.apache.skywalking.apm.dependencies.org.apache.kafka.common.security.authenticator) <init>:62, LoginManager (org.apache.skywalking.apm.dependencies.org.apache.kafka.common.security.authenticator) acquireLoginManager:105, LoginManager (org.apache.skywalking.apm.dependencies.org.apache.kafka.common.security.authenticator) configure:147, SaslChannelBuilder (org.apache.skywalking.apm.dependencies.org.apache.kafka.common.network) create:146, ChannelBuilders (org.apache.skywalking.apm.dependencies.org.apache.kafka.common.network) clientChannelBuilder:67, ChannelBuilders (org.apache.skywalking.apm.dependencies.org.apache.kafka.common.network) createChannelBuilder:99, ClientUtils (org.apache.skywalking.apm.dependencies.org.apache.kafka.clients) createInternal:426, KafkaAdminClient (org.apache.skywalking.apm.dependencies.org.apache.kafka.clients.admin) create:59, Admin (org.apache.skywalking.apm.dependencies.org.apache.kafka.clients.admin) create:39, AdminClient (org.apache.skywalking.apm.dependencies.org.apache.kafka.clients.admin) prepare:58, KafkaProducerManager (org.apache.skywalking.apm.agent.core.kafka) lambda$prepare$1:105, ServiceManager (org.apache.skywalking.apm.agent.core.boot) accept:-1, 783191662 (org.apache.skywalking.apm.agent.core.boot.ServiceManager$$Lambda$6) accept:183, ForEachOps$ForEachOp$OfRef (java.util.stream) end:357, SortedOps$SizedRefSortingSink (java.util.stream) copyInto:483, AbstractPipeline (java.util.stream) wrapAndCopyInto:472, AbstractPipeline (java.util.stream) evaluateSequential:150, ForEachOps$ForEachOp (java.util.stream) evaluateSequential:173, ForEachOps$ForEachOp$OfRef (java.util.stream) evaluate:234, AbstractPipeline (java.util.stream) forEach:485, ReferencePipeline (java.util.stream) prepare:103, ServiceManager (org.apache.skywalking.apm.agent.core.boot) boot:44, ServiceManager (org.apache.skywalking.apm.agent.core.boot) premain:133, SkyWalkingAgent (org.apache.skywalking.apm.agent) invoke0:-1, NativeMethodAccessorImpl (sun.reflect) invoke:62, NativeMethodAccessorImpl (sun.reflect) invoke:43, DelegatingMethodAccessorImpl (sun.reflect) invoke:498, Method (java.lang.reflect) loadClassAndStartAgent:386, InstrumentationImpl (sun.instrument) loadClassAndCallPremain:401, InstrumentationImpl (sun.instrument) ``` -- This is an automated message from the Apache Git Service.
