Apache Dubbo Component

Java SDK (apache/dubbo)

Dubbo Version

Dubbo Java 3.3.7-SNAPSHOT, OpenJDK 23.0.2, macOS 15.7.3

Steps to reproduce this issue

Run tests in the dubbo-rpc/dubbo-rpc-dubbo using NonDex: mvn edu.illinois:nondex-maven-plugin:2.2.1:nondex -pl dubbo-rpc/dubbo-rpc-dubbo -Dtest=org.apache.dubbo.rpc.protocol.dubbo.status.ThreadPoolStatusCheckerTest#test -DnondexRuns=10

About 50% of the time, the test will fail.

What you expected to happen

The test should have passed. NonDex shuffles internal collection order in a way that is acceptable by Java specifications. This test relies on Map<String, Object> being in insertion order during iteration, which happens to succeed most of the time due to the limited nature of the test.
