For Linux System (testing on Redhat7.2), DialogInput and MonoSpaced fonts on Italic style don't work within Textfield under some font sizes (such as: 8,10,12,14,18 and 24).
Tested build: hopper j2sdk b18 on Redhat 7.2 with de_DE locale

Steps to reproduce:
1) login Redhat7.2 with de_DE locale
2) install j2sdk b18 and GlobalSuit v1.3-b09 (/net/sqesvr/export/i18n/i18n_hopper_ws/bundles/v1.3/b09/gs13-b09.tar.gz)
3) run: For DialogInput Font
sh run_gs.sh -jdk:/../j2sdk1.4.1 test/font-render/awt/one/TextFieldRenderTest4.java
or For MonoSpaced Font
sh run_gs.sh -jdk:/../j2sdk1.4.1 test/font-render/awt/one/TextFieldRenderTest5.java
4) the window come up and DialogInput or MonoSpaced Fonts on Italic style display as plain styles for size: 10,12 and 24.
