If you run |make test TEST=jtreg:gtest/GTestWrapper.java| but had not
built using the gtest framework, you would just get a result like this:
|STDERR: java.lang.Error: TESTBUG: the library has not been found in

This is not very helpful in analyzing the problem. I have added a
helpful suggestion to the exception.
