Is the java.awt.Font class thread-safe?

[Frank LaRosa]

Hi,

Is the Font class thread-safe? In particular I'm concerned about
calling the functions "canDisplayUpTo" and "deriveFont" concurrently
on the same Font object.

I realize that Swing and Awt aren't thread-safe in general, but I'm
using this in a strictly non-GUI application. Thanks.

In general, if it doesn't say so in the API documentations, a
method/class is not thread save by definition. It might be by accident,
but I would not bet on this. It might also happen that someone has just
forgotten to document thread-safety (the API docs are notoriously bad
at documenting threading behavior).

But by looking at Font, I would bet it hasn't been designed for
thread-safety at all.
