mapper-locations logic is broken in container deployments if locations match existing package path

[franck102]

MyBatisRecorder fails to resolve the mapper XML files if a location is also a package name. This hit me when doing my first container build, where Quarkus generates some synthetic classes in a separate jar - pls see example below.

This could be addressed in documentation, using locations that don't clash with package names resolves the issue.

• Configuration:
  quarkus.mybatis.mapper-locations=com/acme/core/mapping,...

• Where Quarkus should find the XML mapper file:

Thread.currentThread().getContextClassLoader().getResource("com/acme/core/mapping/account-mapper.xml")
jar:file:/deployments/lib/main/com.acme.ep-core-1.0-SNAPSHOT.jar!/com/acme/core/mapping/account-mapper.xml

• Where it goes instead with the logic in buildFromMapperLocations:

Thread.currentThread().getContextClassLoader().getResource("com/acme/core/mapping")
jar:file:/deployments/quarkus/generated-bytecode.jar!/com/acme/core/mapping
