The file compiles with zero errors under\n`mvn test-compile`. The BUILDPATH failures cascade into synthetic `IMPORT`, `TYPE`, and `MEMBER`\nerrors, making the file appear completely broken when it is not.\n\n## Minimal example\n\n**pom.xml dependency** (the trigger — any pre-Java 9 jar works):\n```xml\n<dependency>\n    <groupId>org.codehaus.jackson</groupId>\n    ",
