Text Field missing last line with MingLiU and font size less than 10

[ivan-lau]

The last line of a data field (Text Field) is missing if the following criteria are fulfilled (JasperReport version 5.6):

1. Font of the field is MingLiU/PMingLiU

2. Font size less than 10

3. Data field contains data more than 5 lines

4. Set "Stretch With Overflow" to true

5. Render to PDF

It seems that the field height is calculated incorrectly when the text field is overflow such that the last line does not have sufficient space for display. The problem can be easily reproducible with the below template.

The only thing that I can get around with this problem is to use font size greater than 9 when using Chinese character.

Font MingLiU with Size = 10. All ten lines could be displayed.

Font MingLiU with Size = 9.  The last line (line10) could not be displayed.

Am I missing something? Or is it a bug? Thank you in advance for any help.
