GYjack created SCB-2312:
---------------------------
Summary: The UT TestVertxMetersInitializer may fail when the test
server is assigned a 4-digit port number
Key: SCB-2312
URL: https://issues.apache.org/jira/browse/SCB-2312
Project: Apache ServiceComb
Issue Type: Bug
Components: Java-Chassis
Reporter: GYjack
The key code line is at
[servicecomb-java-chassis/metrics/metrics-core/src/test/java/org/apache/servicecomb/metrics/core/TestVertxMetersInitializer.java|https://github.com/apache/servicecomb-java-chassis/blob/a063df553aaa0cbdefce4c7f5aaeabba7cc1d466/metrics/metrics-core/src/test/java/org/apache/servicecomb/metrics/core/TestVertxMetersInitializer.java#L169]
Line 169 in
[a063df5|https://github.com/apache/servicecomb-java-chassis/commit/a063df553aaa0cbdefce4c7f5aaeabba7cc1d466]
in the end of this line, the port number is filled into a place holder
{{%-5s}}, which means if the port number is 4-digit, there will be a space at
the end. But if a microservice instance is actually assigned a 4-digit
portnumber, the metrics log will only write the port number without any
unnecessary space character.
