Start by running org.eclipse.jdt.text.tests.SemanticHighlightingTest.enumHighlighting on the win32-java17 configuration. Read SemanticHighlightingTest.java around line 270 and AbstractSemanticHighlightingTest.java around line 113 to identify why two positions are found instead of one; done means the test passes with the expected count.
