It looks like the path content of META-INF/versions/ in one of my dependency jars is incomplete. I am currently checking my dependency list.

[houkunlin]

At present, it is found that the META-INF/versions/ path of dubbo-3.2.13.jar is suspected to not meet the conditional content of

spring-boot/spring-boot-project/spring-boot-tools/spring-boot-loader/src/main/java/org/springframework/boot/loader/jar/MetaInfVersionsInfo.java

Line 84 in 45f09df

int slash = name.indexOf('/', META_INF_VERSIONS.length());

, resulting in a -1 value.

[wilkinsona]

Thanks, @houkunlin. That's exactly it. The code expects entries beneath META-INF/versions/ to be of the form META-INF/versions/<number>/*. The Apache Dubbo 3.2.13 jar has several entries that don't match this expectation:

MetaInfVersionsInfo needs to be updated to tolerate these unexpected entries by ignoring them.

It was found that the previous version 3.2.3 was running normally. During this period, this check code did not seem to have changed.

You're using a different version of Apache Dubbo there. 3.2.11 does not have Multi-Release: true in its manifest but 3.2.13 does. As a result of this different, you won't see the problem with 3.2.11.

Got it, thanks @wilkinsona
