If the required font is missing, the test simply returns early, and the test ends up passing, which is incorrect. Ideally, it should throw a jtreg.SkippedException when the necessary preconditions are not satisfied.

Ideally, when GUI components are created in code running on a headless machine, a HeadlessException should be thrown. However, since MyanmarTextTest.java exits before reaching the point where the GUI is created (due to unmet preconditions), it incorrectly reports a pass. This behavior may lead to a misinterpretation of the test as being headless, which it is not.
