Hi, community!
I found for java.awt.Font.hasUniformLineMetrics() RI returns false for all
fonts (physical/logical) while Harmony returns true for physical and false
for logical.
Spec says: "Checks whether or not this Font has uniform line metrics. A
logical Font might be a composite font, which means that it is composed of
different physical fonts to cover different code ranges. Each of these fonts
might have different LineMetrics. If the logical Font is a single font then
the metrics would be uniform. ". Thus I find reasonable to return true for
physical fonts, as they are single.I assume that it is a non-bug difference
from RI.
Any thoughts on this issue?
Regards,
Ilya.

Issue Type: Bug
Components: Non-bug differences from RI
Environment: Windows XP
Reporter: Ilya Okomin
Priority: Trivial
According to the specification method must Font.hasUniformLineMetricsreturn
true if this Font has uniform
line metrics; false otherwise.
RI returns false for physical font "Arial" while Harmony returns true.

assertEquals(f.getFamily(), name);
assertTrue(f.hasUniformLineMetrics());

I would suppose that it is RI bug, since spec says: " If the logical Font
is a single font then the metrics would be uniform." In this case we have
"Arial" font that is a single physical font on Windows platform and
according to spec it has to have uniform metrics.
