Github user ottobackwards commented on the issue: https://github.com/apache/commons-lang/pull/311 the static factory, is pretty straight forward. The try with resources, less so. What ends up happening is you cannot stop the watch before visiting the nodes. For example, this is what you want to do if you are going to time, but visit later: ```java @Test public void testTryWithResources() { final StopWatch stopWatch = new StopWatch(); try(StackWatch<String,String> watch = new StackWatch<>("testStackWatch")) { watch.start(); stopWatch.start(); stopWatch.stop(); } watch.visit(new StackWatch.TimingVisitor<String,String>() { @Override public void visitTiming(int level, List<String> path, StackWatch.Timing<String,String> node) { assertTrue(node.getStopWatch().getNanoTime() > stopWatch.getNanoTime()); } }); } ``` but it won't work/compile with try with resources
