Re: GWT 2.10.0 release

2022-06-27 Thread RT 
Great to see this progress. Updated my project to 2.10 from 2.9, the only 
issue so far was removing the ie10 user agent in the gwt.xml, 
leaving safari,gecko1_8

Not these values are for running HTMLUnit, not for GWT compiler.

GWT 2.10.0 user.agent values are 

   - gecko1_8: Used for FireFox and IE 11
   - safari: Used for everything based on WebKit (Safari, Chrome, Edge, 
   Opera, ...)

Re: Internal Compiler Failure when trying to upgrade a GWT 2.7.0 application to 2.8.1

 This line indicates that you have some version of JDT / ECJ on your 
classpath during GWT compilation that is incompatible with the one that GWT 
compiler uses. JDT is embedded in gwt-dev.jar so it is possible that some 
other dependency brings in a different version.

Internal Compiler Failure when trying to upgrade a GWT 2.7.0 application to 2.8.1

2022-06-27 Thread mmo 
I am trying to upgrade an application still using GWT 2.7.0 to at least 
2.8.1 (and if possible higher, i.e. 2.9.0 or ideally 2.10.0).

After raising the GWT version from 2.7.0 to 2.8.1 the compilation of the UI 
maven module now always ends in an internal compiler failure:

ANY idea or hint anyone, how to analyze this? Or how to figure out what 
could be causing this and where to start searching???

What are legal "user.agent=" values?

2022-06-27 Thread mmo 
I was trying to update our application from GWT 2.8.1 to the new GWT 2.10.0.
The first compilation failed with the eror message that ie10 was not a 
legal user.agent value (we had indeed used that value, since it was the 
newest IE version available).

So - according to the release notes which mention “FF”, “Chrome”, “IE” (for 
IE11), “Edge”, and “Safari” as new user.agent values I changed that to 
"Chrome, Edge". 
The subsequent compilation then succeeded but when starting up the 
application I get the error:

[INFO]  [ERROR] Line 21: Value 'Chrome' in not a valid value for 
property 'user.agent'
[INFO]  [ERROR] Line 21: Value 'Edge' in not a valid value for 
property 'user.agent'

Thus my question: what *are* the new valid user.agent values? Do they have 
to be in all-lowercase (as the old ones) or what exactly can or does one 
have to enter here?
