Q: I installed last version of RPC (Luna Release (4.4.0) Build id: 20140612-0600), configured my project (see details in attachments), and it doesn't work. Something tells me, that it is a software problem on my workstation. But i checking my configuration again and again and i really have no idea what is it. All errors are in attachment file ("stack trace.551").

Info:

JavaFX was installed by maven.
(mvn com.zenjava:javafx-maven-plugin:2.0:fix-classpath)

[Sys params]
java version "1.7.0_71"
Java(TM) SE Runtime Environment (build 1.7.0_71-b14)

Is there any special reason you want to use Java 1.7 and, hence, JavaFX 2.2 ?

If I'm not mistaken, Efxclipse targets only Java 1.8 (and JavaFX Cool

Cause it is quite an old project and earlier it worked with this preferences.

And i'm sure it doesn't matter what java version it is. Because it gave quite a same result with java.version=1.8.0_25 for me (some problems were gone, however main problem still here). See "stack trace.557".

And i really don't want to change JFX version yet, because suddenly this would lead to big problems.

Did you do a package import for javafx.scene.embed.swt?

The hook bundle still aupports java7 - only the higherlevel runtime stuff is java8 which IMHO was a good decision which payed of in the 1.2 release already where we've be able to evolve interfaces with break the API contract wohoo java8 rocks

No, we didn't. We used extension of org.eclipse.fx.ui.workbench3.FXViewPart

If you mean "javafx.embed.swt", FXViewPart (org.eclipse.fx.ui.workbench3.FXViewPart) already imported it.

Hi,

Could you try starting with -Defxclipse.osgi.hook.debug=true. This
should give you some debug information on the OSGi-Hook.

One thing that could be on Linux is that you are launching with SWT-Gtk3
which is not supported by JavaFX and so we refuse to load the
swt-embedding code but this should have led to another exception which I
can't find in your stacktrace

Anyways turn on this option and provide us the output which start with

FXModuleClassloader...... or FXClassLoader......

The rest of the output is not important.

Ok yeah my guess was right - see

So you need to force SWT to use Gtk2! e.g. by setting SWT_GTK3=0 in the
launcher environment, not sure the --launcher.GTK_version works when
starting a inner instance.

Oh, Tom, great thanks for help.

After set param SWT_GTK3=0 in the launcher environment, everything work fine again.
