error

An example without twr
- create a breakpoint on the indicated line
- Debug as > Java application
- when the breakpoint is hit, uncomment the indicated line
- debugger jumps to beginning of foo() => GOOD !
-------------------------------------------------------------------------------
class Try {
	public static void main(String[] args) throws Throwable {
		foo();
	}

	private static void foo() {
		System.out.println("1");
		Test t = new Test();
		//Test t1 = new Test();  // uncomment this line after breakpoint is hit
		try {
			String line = "";  // breakpoint on this line
			System.out.println(line);
		} finally {
		}
	}

	private static class Test {
		public Test() {
			System.out.println("constructor");
		}
	}
}
