PDFBox TextPostion.getHeightDir() gives 4 times the actual height only for font cambria

Hi all,
I am using PDFBox 1.8.2 PDFTextStripper. I noticed that if the pdf file has
Cambria font the height of the text position is completely wrong. It turns
out that the height is exactly 4 times the actual height.
I have attached the test pdf file I used and also find below the output
from my program for each char in the pdf. Its a simple pdf which has the
word cambria in different font sizes.
I have tested with all other fonts and it gives me perfect height but why
cambria fails ?

As you can see for font size 72 the height was 200.88 but the actual height
is 50.22 which is 200.88 / 4

Due to some restrictions your pdf didn't  make it. Please send either a link to
a download location (shared hoster or something similar) or create an issue on
JIRA [1] and attach the pdf in question.
