I have noticed that ajc does significantly worse at isolating/recovering from compiler errors than javac. For example, on a recent project build of a pure Java file, I was refactoring to change the return type of a method, but I forgot to delete the void return. So the single compiler error was this line: protected void FailureStats addFailure(FailureDescription failureDescription) { ajc reports about 35 compiler errors (!) from this one problem. By contrast, I recompiled this code in a test Java project and Eclipse's Java compiler and it had four, useful errors that would make the problem easy to track down: Severity Description Resource In Folder Location Creation Time Id 2 The method addFailure(FailureDescription) is undefined for the type PerfStatsImpl PerfStatsImpl.java testajccompiler/src/glassbox/track/api line 360 February 15,

our poor parser recovery is already covered by bug 42660, this is another case. *** This bug has been marked as a duplicate of 42660 ***
