InvocationTargetException when running rest general client code

[mon...@gmail.com]

when running the rest example general client code module, 80% of the times an exception occurs in the console.

The fx browser window then turns black. When changing the layout, the application screen appears for a split second before turning black again.

In general the javafx browser needs quite a long time to load the page (5 seconds before general layout appears, 20+ seconds before text appears), while normal browser and android app load much faster.

Hello Timon.

The black screen issue may be related to
https://netbeans.org/bugzilla/show_bug.cgi?id=236961

the fix should be on NetBeans 8.0.x AU in few weeks.

The "Problems copying method. Incompatible JVM?"

problem is related to springloaded. It should be just a warning. In case you want to avoid it, you can disable use of springloaded during exec:exec in the pom.xml

Thanks, I will check with the nightly build.

np, I will consider it a warning.

I was wondering if that error was causing the slow loading, but does not seem related.

Cheers,

Fixed in nightly NetBeans build 

I was wondering if that error was causing the slow loading, but does not seem related.

for the record, slow loading was caused by slow internet connection in combination with css import:

@import url("http://fonts.googleapis.com/css?family=Open+Sans:400,400italic,600,600italic,800,800italic");

so not related to dukescript ;)

Cheers.
