--------------------------------------------------------------

So, I decided to be a good citizen and make a test project, and in my test project, I'm seeing
the expected output. I'm unclear on why I wasn't earlier. I'll do some more research and update
this as soon as I know more. In the meantime, please don't close as Can't Reproduce or whatever.
Thanks! :)

>                 URL: https://issues.apache.org/jira/browse/MCOMPILER-325
>             Project: Maven Compiler Plugin
>          Issue Type: Bug
>    Affects Versions: 3.7.0
>            Reporter: Jake Robb
>            Priority: Minor
>
> Context: [https://stackoverflow.com/questions/48775213/maven-compilation-error-without-any-errors-from-the-compiler]
> If the Java code being compiled contains a chain of method calls that is too long to
fit in javac's stack, javac will throw a StackOverflowError and exit.
> The resulting output indicates that javac errored, but does not show the SOE, nor which
source file caused it. (It'd be nice if it actually pointed out the problem, but that's on
javac, not on the Maven plugin.)
> For more recent versions of the plugin, if {{verbose=true}}, the plugin output includes
the files being compiled as they go, and so the last file output is helpful, but it still
doesn't indicate what went wrong. -X and -e args to Maven are also not helpful.
> In my case, the failure occurred using default settings for stack size (I think it's
1MB) when compiling a test case that chained together 673 builder methods, e.g.
> {code:java}
> return new MyBuilder().foo(a1).foo(a2).foo(...).foo(a672).foo(a673).build();{code}
> I assume this problem is not unique to StackOverflowErrors and would affect any thrown
Error from javac.
> The plugin should be updated to capture javac's error output and include it when applicable.
