it's clearer to do 

`if (len < 0) {
      break;
}`

it also matches the style at line 83

If you're setting this field in both reader and writer threads, is there a 
chance that one overwrites the other? 

Thinking about debugging this if the test fails... in the event of a error, 
should each thread print its stack trace and then set failed to true. Then at 
the end of the test, if failed is true, throw a RuntimeException with a generic 
message that something failed?

To aid debugging a failure, it might help to include the number of certificates 
that were read.
