Thank you for your help. I'm using CompletableFuture et al from https://github.com/nordligulv/gwt/commit/ea70c5358bac3c939cb0c1628a58ccc462cd7423
I've stepped into the function in chrome and the CompletableFuture is working correctly and being compiled to a Promise. The offending lambda is about to be passed into the promise's then function. The source root for the emulation classes I'm using is: https://github.com/Peergos/Peergos/tree/google/src/peergos/gwt/emu I was originally using 2.8rc1, but there were other issues which were fixed by moving to the HEAD in github (commit 8a1632911) On Tuesday, 6 September 2016 21:54:02 UTC+1, harshyadav wrote: > > From a quick look at your code, not sure how are you compiling your class > HTTPCoreNode.java > <https://www.google.com/url?q=https%3A%2F%2Fgithub.com%2FPeergos%2FPeergos%2Fblob%2Fgoogle%2Fsrc%2Fpeergos%2Fshared%2Fcorenode%2FHTTPCoreNode.java&sa=D&sntz=1&usg=AFQjCNGhSP3hN_ugLqtGZ6Dkg2NRlQFruA> > using > GWT (CompletableFuture and most of java.util.concurrent classes are not > emulated in GWT). > But, client side, we have been using Lambdas with no issues with 2.8rc1 > (and 2.8beta-1 before that), can you try if it works with with that? > > > On Tuesday, September 6, 2016 at 4:29:46 PM UTC-4, Ian Preston wrote: >> >> This is the Function interface code: >> >> https://github.com/Peergos/Peergos/blob/google/src/peergos/gwt/emu/java/util/function/Function.java >> >> On Tuesday, 6 September 2016 21:00:11 UTC+1, harshyadav wrote: >>> >>> Can you share your functional interface code? >>> >>> On Tuesday, September 6, 2016 at 3:35:32 PM UTC-4, Ian Preston wrote: >>>> >>>> Thank you for all your awesome work on GWT. >>>> >>>> I'm getting a lambda being compiled to an empty method.
