RemoveRedundantTypeCast removes too much

[koppor]

We have a code base soon 20 years old - and not all code was modernized.

When from 6.4.0 to 6.5.4 and BOM to 2.5.0 - JabRef/jabref#10650, OpenRewrite changed too much:

        private static final List<Character> DISALLOWED_CHARACTERS = Arrays.asList('{', '}', '(', ')', ',', '=', '\\', '"', '#', '%', '~', '\'');

        String newKey = key.chars()
                           .filter(c -> unwantedCharacters.indexOf(c) == -1)
-                           .filter(c -> !DISALLOWED_CHARACTERS.contains((char) c))
+                           .filter(c -> !DISALLOWED_CHARACTERS.contains(c))
                           .collect(StringBuilder::new,
                                   StringBuilder::appendCodePoint, StringBuilder::append)
                           .toString();

         private final Deque<Object> stack;

-        stack.push((int) s.charAt(0));
+        stack.push(s.charAt(0));

Tests fail after this improvement. Not sure whether it's just a hint to modernize the code also at these places. I just wanted to report it to make it more googable. No need to resolve it.

My workaround is to disable the recipe.

I know the issue is a bit old. Just came up with a unit test case for the second example given. And the good news is that the test passes, which I assume is thanks to some other changes in the code base:

    @Test
    void primitives() {
        rewriteRun(
          //language=java
          java(
            """
              import java.util.Deque;

              class Test {
                  Deque<Object> stack = null;

                  void method(String s) {
                      stack.push((int) s.charAt(10));
                  }
              }
              """
          )
        );
    }

@koppor, it seems like this issue is no longer affecting the https://github.com/JabRef/jabref codebase. So I thought I would contribute back by raising JabRef/jabref#12827, but it seems like I don't have all the setup needed, etc. Maybe you can take it from there?

[greg-at-moderne]

Closing the issue as it seems the problem no longer occurs, although I haven't been able to pinpoint the exact change which fixed that.

With version 3.2.0; I cannot update to 3.4.0 due to 3a05d87

I will wait for a next release and either open a new or be silent ^^

[greg-at-moderne]

Thanks for checking.

I cannot update to 3.4.0 due to 3a05d87

What's wrong with this? I am not sure what is the impact on your project.

I think, the recipe was updated from 3.2.0 onwards.

PR trying to update from 3.2.0 to 3.4.0: JabRef/jabref#12766

Itis very OK for me to wait for a new release.

I tried today.

Same diff.

To reproduce:

1. Checkout Bring back remove redundant type cast check from OpenRewrite JabRef/jabref#12827
2. Merge upstream/main
3. Execute ./gradlew run
4. Maybe: git reset --hard upstream/main
5. Re-enable - org.openrewrite.staticanalysis.RemoveRedundantTypeCast
6. Execute ./gradlew rewriterun
7. Execute ./gradlew run

I tried to execute it on the moderne platform --> https://app.moderne.io/recipes/org.openrewrite.staticanalysis.RemoveRedundantTypeCast?organizationId=ZjhkMzFkYmMtOTE5Yi00ODgwLThjMDItMDkwMThmYzhmODMz

However, there is no ./gradlew assemble task executed, is it?

[Siedlerchr]

Still an error with
id 'org.openrewrite.rewrite' version '7.3.0'
and
org.openrewrite.recipe:rewrite-recipe-bom:3.5.0

Re-opening based on the feedback above.
Thanks for providing the fresh input.
