I don't know when (or whether, but that's likely) there will be a 2.8.3 
release, this fix has been backported 
already:

The fix for this bug got backported to the 4.7 line of Eclipse. Will there 
be a 2.8.3 GWT release and do you guys plan to upgrade to this version of 
JDT if so?

[Ignacio Baca Moreno-Torres]

Yep, IMO the best compromise between solution & risk is to apply the patch
over the last CUSTOM JDT build and wait for java9 lang support to upgrade
to the last JDT.

 The bug has been already solved. It needs to be merged and release in

 Do I create an issue in github? What do you think it is better, to just
 add the patch (as I have done) over the last version, or to upgrade to last
 JDT?

 PD: this will improve a bit compilation times and memory consumption ;).

Seems like a good reason to defer to GWT 2.9.

I would wait until an eclipse jdt release is done and upgrade JDT.

[gwt-contrib] Super slow compilation in projects with many wildcard generics

[Ignacio Baca Moreno-Torres]

JDT has a bug (https://bugs.eclipse.org/bugs/show_bug.cgi?id=521438) that 
make it super slow to compile some project involving wildcards generics. 
Actually, there are many problems with performance and memory consumption 
since Java 8, this has just lived longer bc it was a bit more difficult but 
seem to be a combination of wildcard+inheritance that makes the internal 
type map to explode. RxJava 2 takes >3min to compile caused by this bug so 
it makes impossible to work with.

The bug has been already solved. It needs to be merged and release in JDT 
and later on, it will be nice to be merged in the GWT JDT version as soon 
as possible, anyway as this seems to be a long process I have already 
released a patched version here.


rxjava-gwt-repo

https://raw.githubusercontent.com/intendia-oss/rxjava-gwt/mvn-repo/



The patched commit is this 
one 
https://github.com/ibaca/eclipse.jdt.core/commit/995495659bddcaf193c0107f8489e698624ceea7
And applied in GWT 
here 
https://github.com/ibaca/gwt/commit/63218f3d695cfc6ec20fea776908b9801952f462

Do I create an issue in github? What do you think it is better, to just add
