This test used to fail differently until b137 (see JDK-8144015) but now on both my systems (10.10 and 10.12) it throws
tlbounds=java.awt.geom.Rectangle2D$Float[x=-1.09375,y=-23.125,w=83.578125,h=27.75]
gvbounds=java.awt.geom.Rectangle2D$Float[x=-1.09375,y=-23.125,w=83.265625,h=27.75]
outlineBounds=java.awt.geom.Rectangle2D$Float[x=-1.09375,y=-23.125,w=83.578125,h=27.75]
java.lang.RuntimeException: Bounds differ [gvv != tl]

i.e. width is different. I don't know how important is the difference in quarter of a pixel, in this context, so I refrain from making it a testbug. Please decide.
