In the explanation of option two "only for package named TestClass" should be likely "only for class named TestClass"?

No, package is correct. http://docs.oracle.com/cd/E19683-01/806 ... index.html

HTH,

Maybe I missed something, but my understanding was that to enable assertions for some package, the postfix "..." should be used. In this case we have "java -ea:TestClass" which seems to indicate that we would like to enable assertions for the class TestClass, and it would be "java -ea:TestClass..." that would enable assertions for a package called TestClass

The link you suggested seems to indicate the same: With one argument ending in "...", assertions are enabled in the specified package. and With one argument not ending in "...", assertions are enabled in the specified class.

You are right. I misread. Very sorry about that
