Hi,
From "JLS 7.7"
Which compilation units are observable is determined by the host system.
However, all the compilation units of the package
java and its subpackages lang and io must always be observable. The observability of a compilation
unit influences the observability of its package (�7.4.3).
Can somebody please tell what is the meaning of Observability for a package and what is the effect of that.
Regards,
Abhinav
