sormuras edited a comment on issue #28: MCOMPILER-359 - Fix for NPE URL: https://github.com/apache/maven-compiler-plugin/pull/28#issuecomment-566862745 This is line that yields the NPE: https://github.com/apache/maven-compiler-plugin/blob/maven-compiler-plugin-3.8.1/src/main/java/org/apache/maven/plugin/compiler/TestCompilerMojo.java#L254 The initial value assigned "cause" is tested for being "null": ``` 253: Throwable cause = pathException.getValue().getCause(); 254: while ( cause.getCause() != null ) 255: { 256: cause = cause.getCause(); 257: } ``` Current master branch doesn't differ, i.e. it also will throw a NPE. Robert: Should the initial cause of a "path exception value" always be assigned? If not, just report the path exception without the message pointing to the cause?
