Apache commons-text security issues

Hello, note that commons-text 1.9 used in gwt-user is having security issues, so please upgrade this library to newer version if possible. This jar is used by net.sourceforge.htmlunit library.

Re: Elemental2 oddities

With the Elemental2 1.4.0-RC1 release, we now have a new WebGLContextAttributes class that now has a create method.

However, calling it:

WebGLContextAttributes contextAttributes = WebGLContextAttributes.create();

Results in:

com.google.gwt.core.client.JavaScriptException: (ReferenceError) : mOu_g$ is not defined

Which isn't what I expected.

Doing this still works:
WebGLContextAttributes contextAttributes = Js.uncheckedCast(JsPropertyMap.of());

I don't have the closure compiler knowledge to understand what's going on here.  Was the fix ( https://github.com/google/closure-compiler/issues/4250 ) not correct?

Because it is only a dictionary (= a plain JS object)

https://registry.khronos.org/webgl/specs/latest/1.0/#5.2

In JS you simply do:

var canvas = document.getElementById('canvas');
var context = canvas.getContext('webgl', { antialias: false, stencil: true }); // 2nd argument is WebGLContextAttributes
var attributes = context.getContextAttributes();

Looks like it is again defined badly in closure-compiler externs. The generated elemental2 implementation should have a similar structure than for example elemental2 AddEventListenerOption. It is an interface with a static create() method which does exactly what you do in your solution.

See:

https://github.com/google/closure-compiler/blob/dc7f38bb0528b011984ef33a448c7941cf7e0b88/externs/browser/webgl.js#L2918

I think it should be @interface or @record instead of @constructor.

I'm switching to use Elemental2, and it's fantastic.  All the bindings I'll ever need.  A big thank you to all that created it!

There are some strange things though.  Like when setting up a WebGLRenderingContext, we need to pass WebGLContextAttributes.

However, doing:

WebGLContextAttributes contextAttributes = new WebGLContextAttributes();

compiles fine, but at runtime throws:

TypeError: $wnd.WebGLContextAttributes is not a constructor

I figured out I can do this instead:

WebGLContextAttributes contextAttributes = Js.uncheckedCast(JsPropertyMap.of());

But why can't I just use its constructor?  Am I doing something wrong?

Re: Elemental2 WebRTC createOffer and createAnswer are incorrect

It took a year, but the newly released Elemental2 1.4.0-RC1 now has this fix.  🎉

Now the good people at the closure-compiler have fixed the error ( https://github.com/google/closure-compiler/commit/5aadfa78592a2778ae4cac52613fb9238228b3e8 ), I see I can build a new version of Elemental2 locally ( https://github.com/google/elemental2?tab=readme-ov-file#build-gwt-compatible-maven-jar-files ).

It would be nice to get an offical Elemental2 build, and have it pushed to Maven.  It looks like one hasn't been done for 9 months, is there any offical Elemental2 release schedule?

And this works great.  But it would be nice to fix Elemental2.

You have to file an issue against closure-compiler because elemental2 takes their definition: https://github.com/google/closure-compiler/blob/15c5dd492cbb9dcdfd24d01f75b64e3e9b2291eb/externs/browser/w3c_rtc.js#L3586C23-L3586C44

Re: GWT 2.13.1 released

Looks good here too (rebuild with GWT 2.13.1 SDK in Eclipse 2026-06 with the GWT Eclipse Plugin).

This is a small bugfix release, with four changes:

• Permit failure to delete files on Windows, and close finished logs. This is a regression, caused by trying to use Guava to replace some bespoke utility classes.
• Simplify RTA iframe loading in Firefox. This addresses a change in behavior in Firefox, although in most cases applications compiled with older versions of GWT should have a workaround automatically applied by Firefox.
• Use Objects.equals to compare record fields for null support. As the current implementation of records was producing an incorrect equals method and this was a low risk fix, this was backported.
• Include GWT version, commit in JFR output. This ensures that we have a baseline for compiled size improvements going forward.
