Not sure removing the build directives was the right way to go. As per the jtreg tag guide:

> A test that relies upon library classes should contain appropriate @build directives to ensure that the classes will be compiled. It is strongly recommended that tests do not rely on the use of implicit compilation by the Java compiler. 

so the problem is likely caused by missing build directives in the test(s) that fails.
