### Search before asking - [x] I had searched in the [issues](https://github.com/apache/skywalking/issues?q=is%3Aissue) and found no similar issues. ### Apache SkyWalking Component Java Agent (apache/skywalking-java) ### What happened When I inject skywalking java agent in a scala project，I found no trace segment send to skywalking oap server. And skywalking UI has nothing except service and instance info. skywalking-agent/logs/skywalking-api.log content is: `DEBUG 2025-04-25 07:51:27.696 grpc-nio-worker-ELG-1-4 org.apache.skywalking.apm.dependencies.io.grpc.netty.NettyClientHandler : [id: 0xe53eb218, L:/172.19.208.30:43384 - R:skywalking.observability.svc/10.2.70.166:11800] INBOUND HEADERS: streamId=4817 headers=GrpcHttp2ResponseHeaders[:status: 200, content-type: application/grpc, grpc-encoding: identity, grpc-accept-encoding: gzip, x-envoy-upstream-service-time: 0, date: Fri, 25 Apr 2025 07:51:27 GMT, server: envoy] padding=0 endStream=false DEBUG 2025-04-25 07:51:27.696 grpc-nio-worker-ELG-1-4 org.apache.skywalking.apm.dependencies.io.grpc.netty.NettyClientHandler : [id: 0xe53eb218, L:/172.19.208.30:43384 - R:skywalking.observability.svc/10.2.70.166:11800] INBOUND DATA: streamId=4817 padding=0 endStream=false length=5 bytes=0000000000 DEBUG 2025-04-25 07:51:27.696 grpc-nio-worker-ELG-1-4 org.apache.skywalking.apm.dependencies.io.grpc.netty.NettyClientHandler : [id: 0xe53eb218, L:/172.19.208.30:43384 - R:skywalking.observability.svc/10.2.70.166:11800] INBOUND HEADERS: streamId=4817 headers=GrpcHttp2ResponseHeaders[grpc-status: 0] padding=0 endStream=true DEBUG 2025-04-25 07:51:28.032 grpc-nio-worker-ELG-1-4 org.apache.skywalking.apm.dependencies.io.grpc.netty.NettyClientHandler : [id: 0xe53eb218, L:/172.19.208.30:43384 - R:skywalking.observability.svc/10.2.70.166:11800] OUTBOUND HEADERS: streamId=4819 headers=GrpcHttp2OutboundHeaders[:authority: skywalking.observability.svc:11800, :path: /skywalking.v3.ProfileTask/getProfileTaskCommands, :method: POST, :scheme: http, content-type: application/grpc, te: trailers, user-agent: grpc-java-netty/1.68.1, agent-version: 9.4.0, grpc-accept-encoding: gzip, grpc-timeout: 59999871u] streamDependency=0 weight=16 exclusive=false padding=0 endStream=false DEBUG 2025-04-25 07:51:28.032 grpc-nio-worker-ELG-1-4 org.apache.skywalking.apm.dependencies.io.grpc.netty.NettyClientHandler : [id: 0xe53eb218, L:/172.19.208.30:43384 - R:skywalking.observability.svc/10.2.70.166:11800] OUTBOUND HEADERS: streamId=4821 headers=GrpcHttp2OutboundHeaders[:authority: skywalking.observability.svc:11800, :path: /skywalking.v10.AsyncProfilerTask/getAsyncProfilerTaskCommands, :method: POST, :scheme: http, content-type: application/grpc, te: trailers, user-agent: grpc-java-netty/1.68.1, agent-version: 9.4.0, grpc-accept-encoding: gzip, grpc-timeout: 59999843u] streamDependency=0 weight=16 exclusive=false padding=0 endStream=false DEBUG 2025-04-25 07:51:28.032 grpc-nio-worker-ELG-1-4 org.apache.skywalking.apm.dependencies.io.grpc.netty.NettyClientHandler : [id: 0xe53eb218, L:/172.19.208.30:43384 - R:skywalking.observability.svc/10.2.70.166:11800] OUTBOUND DATA: streamId=4819 padding=0 endStream=true length=95 bytes=000000005a0a1d646f63756d656e742d61692d696e746567726174696f6e2d70722d3135122e646f63756d656e742d61692d696e746567726174696f6e2d7072...
