TsacertOptionTest.java references another file TimestampCheck.java which uses a class in this private package, and compilation fails.

Unfortunately JPRT has not caught this because TimestampCheck.java was executed earlier (which itself is also a @test and includes the property @modules line).

Noreg-self.
