Is that important ? Remember it is conditionally supported functionality ?

test/jdk/java/awt/TextArea/SelectionVisible/SelectionVisible.java line 65:

It probably doesn't matter but I'd like to see disposeFrame called with invokeAndWait
And you could restructure this to be simpler
invokeAndWait(::disposeFrame)
if (!selectedText ...) {
} else {
System.out.println("test passed");
}

and then you only need one call site for the dispose
