After this PR

The build works correctly

Possible downsides?

The commit uses reflection to call the correct method, but this is the only way to support the incompatible API change introduced in JDK 25 while still supporting older JDK.

@crogoz @felixdesouza @CRogers @FinlayRJW anything I can help you with ?

slachiewicz · 2025-06-06T16:33:54Z

@gnodet similar fix was also in google-java-format

gnodet · 2025-06-06T16:53:43Z

@gnodet similar fix was also in google-java-format

Ah, didn't check that one. Both should be fixed I suppose.

slachiewicz · 2025-06-08T08:57:55Z

They fixed it with a static variable, that may perform better

gnodet · 2025-06-08T10:23:42Z

The problem here is more that the team is not responsive at all...
I'm happy to change it to whatever is needed, but if the PR is not applied...

+            try {
+                // Fall back to pre-JDK 25 method (Queue<JCDiagnostic>)
+                Method queueMethod = DeferredDiagnosticHandler.class.getMethod("getDiagnostics");
+                return (Collection<JCDiagnostic>) queueMethod.invoke(handler);
+            } catch (Exception e2) {


I don't believe this particular change does anything? There is no difference between this and lines 480-482. It makes more sense to do the same/equivalent change as google-java-format: https://github.com/google/google-java-format/pull/1247/files.

@felixdesouza You're right, I removed the second fallback which is completely useless.
I also cached the method handle in a static final field to get closer to google/google-java-format#1247. Just cherry-picking their commit could work too I suppose.

talios · 2025-07-16T05:16:41Z

Any chance of seeing this merged/released soon? I'm starting to test our builds under J25ea and this was the first thing I hit.

CRogers · 2025-07-16T10:11:02Z

I've made another PR to apply this change at #1367 - just because some our changelog infra doesn't work well on forks (there's a fix in the works for it but not ready yet)
