Re: Issue with enhanced switch statements in GWT 2.12.1

Could be related to https://github.com/gwtproject/gwt/issues/10044

Fwiw, the issue fixed in 2.12.1 was not about the "case x -> foo" vs "case x -> { foo }" but about enclosing the whole switch inside a block.

For me, they compile, but they don't work.  Eg.  This code:

GWT.log("Test 1 - Start");
switch (1) {
  case 1 -> {
    GWT.log("Test 1 - 1");
  }
  case 2 -> {
    GWT.log("Test 1 - 2");
  }
  case 3 -> {
    GWT.log("Test 1 - 3");
  }
}
GWT.log("Test 1 - Done");

GWT.log("Test 2 - Start");
switch (1) {
  case 1 -> GWT.log("Test 2 - 1");
  case 2 -> GWT.log("Test 2 - 2");
  case 3 -> GWT.log("Test 2 - 3");
}
GWT.log("Test 2 - Done");

Will never get to the last "Test 2 - Done" line.  The output will be:

Test 1 - Start
Test 1 - 1
Test 1 - Done
Test 2 - Start
Test 2 - 1

Is this a known issue?

Thanks.
