java/openjdk8: fix build with clang 19

Clang 19 is now more strict about undefined integral expressions used as
constants in enum, which results in errors compiling java/openjdk8,
similar to:

In openjdk11 and later, the (-1) constants have been replaced by the
unsigned variant (~0u), which fixes these errors.
