compiler errors after upgrade to gwt 2.8.0
Hello, after upgrading a project from GWT 2.7.0 to GWT 2.8.0 I and when compiling with the GWT compiler using the -strict option, I get a lot of errors like this: Tracing compile failure path for type 'java.util.stream.Stream' [ERROR] Errors in 'jar:file:/home/magnus/dvl/lib/gwt-2.8.0/gwt-user.jar!/com/google/gwt/emul/java/util/stream/Stream.java' [ERROR] Line 1113: The method naturalOrder() is undefined for the type Comparator [ERROR] Line 101: The method spliterator() is undefined for the type List> [ERROR] Line 1098: The method naturalOrder() is undefined for the type Comparator [ERROR] Line 1122: The method spliterator() is undefined for the type List [ERROR] Line 181: The method stream() is undefined for the type Set [ERROR] Line 85: The method stream(Object[]) is undefined for the type Arrays [ERROR] Line 185: The method stream(T[]) is undefined for the type Arrays When switching back to GWT 2.7.0, the errors don't appear. Unfortunately, the messages do not point in my code. So how do I have to modify my project in order to solve the problem?

Re: Animating images in GWT
To preload images:
img = Document.get().createImageElement()
img.setSrc(url)
(you could then keep all those ImageElementâ‹…s in a list and use them
directly instead of setHTML)
You can use Image widgets too, which have load event handlers.

Re: Animating images in GWT
Use can use requestAnimaionFrame, as we do. (https://studio.cospaces.io) It has exact and precise timing information in the argument -- You received this message because you are subscribed to the Google Groups "GWT Users" group.

Re: Animating images in GWT
I tried with a timer but the transition is a little slow the first time as
the images download. Is there some way to cache or download them into
memory before iterating them?
// Create a new timer that iterates the images
Timer t = new Timer() {
int counter = 0;
@Override
public void run() {
if (counter < imageUrls.size()) {
iconPreviewHTML.setHTML("");
}
counter++;
}
};
// Schedule the timer to run once in x seconds.
t.scheduleRepeating(500);

Trying to run GWT's own test suite with Java 9 might possibly help understand where the problem comes from. -- You received this message because you are subscribed to the Google Groups "GWT Users" group.

Re: Problem compiling GWT code with Java9
I think it is more a class path / module path issue than a unitCache issue (you can always delete the unit cache or don't use it at all by disabling it on the command line). I guess GWT Compiler simply does not see Core.gwt.xml even though you have inherited it. -- J. -- You received this message because you are subscribed to the Google Groups "GWT Users" group.

Problem compiling GWT code with Java9
At Labkey.com we're trying to compile all of our code, which includes GWT code, with Java9 (due for release in the summer)getting a head start. We have not been able to compile GWT code, which doesn't use any new Java features. We're getting the error [java] Compiling module org.labkey.experiment.property.Designer [java][ERROR] Unable to find type 'java.lang.Object' [java] [ERROR] Hint: Check that your module inherits 'com.google.gwt.core.Core' either directly or indirectly (most often by inheriting module 'com.google.gwt.user.User') We've had an older version of GWT but have tried with the latest 2.8 as well and get the same thing. I've added -logLevel=DEBUG to get more info and the log says we're inheriting all of the appropriate packages, including com.google.gwt.core.Core and com.google.gwt.emul.Emulation, which of course is where java.lang.Object lives. It seems like something is going wrong with gwt-unitCache because the log looks like this: ..lots of inherits before this..
