When looking at the test SOEDeeplyNestedBlocksTest, I noticed that the test crashes javac with a StackOverflowException. And yet, the test seems to pass.

After a closer look I realized that this odd behavior is caused by the test calling `JavacTask::call` w/o checking the boolean result. This API method wraps any exception (except for those originated in client code).

I found many instances of such test (see attached file).
