I have a JButton with text containing .. character & a JCheckBox with text containing : character both the special character are not rendered when screen magnifier is enabled

Step to reproduce :
1) 1) Enable Screen magnifier on theMac
System Preference -> Accessibility -> Zoom -> Select ( Enable Hover Text)
2) Run the attached test with -Djavax.accessibility.screen_magnifier_present=true
3) Move the mouse over the JButton and observe that all the characters on the JButton text is not rendered
4) Move the the mouse over the JCheckBox and observe that : character on the JCheckbox is also not rendered if you see the same then the bug is reproduced.

I have attached screen recording of the same comparing the native application rendering the characters .
