How to justify text when adding glyph rendering property

[spak.flash12]

After I added

net.sf.jasperreports.export.pdf.glyph.renderer.blocks.x=thai  ----- to .properties file

or

<property name="net.sf.jasperreports.export.pdf.glyph.renderer.blocks.x" value="thai"/> ----- to .jrxml file

The text in staticText element boxs are not justified anymore. Eventhough I set the textAlignment="Justified"

<textElement textAlignment="Justified">...</textElement>

Is there alternative to this without removing the property? Thank you for your help.
