I am on vacation for (another) week but it is possible that what
you are describing is a bug whereby a transformation that is in effect
was not inverted before returning metrics to the application.
https://bugs.openjdk.java.net/browse/JDK-8139178
This notably affected rotations but could be in play here too although
I haven't tested this. It was fixed very recently so you will need to try a
JDK 12 EA build here : https://jdk.java.net/12/

Philip,
Default scaling options are "Medium - 125%" on Windows 7. You are
correct this does affect things but read on...
Basically, we are using these FontMetrics values to determine a scale
transformation to apply to a size 12 font. HDPI might be playing in
somewhere here, but the problem we know about is with our use of
FontMetrics.
I wrote some code to demonstrate our problem (source at the end of
this message). The application shows:
·An example string drawn using
java.awt.Graphics#drawString(java.lang.String, int, int) with a
"normal" font object: Calibri plain, size 12
·The same string drawn based on a Font that is "scaled" (nothing to do
with HDPI) using a simplified version of what our application does
with the FontMetrics object (we also have zoom levels and users may
specify their font sizes in various ways)
·2 rectangles with sizes hard-coded to wrap these texts when run on my
system with OracleJDK 8 (what our applications currently use), for use
when comparing the screenshots
