B4J Question Can't test B4J

[GGSoft]

As an intensive user of B4A and B4i I decided try B4J. I tried to run an "empty" project (by "empty" I mean "as born") and I get an horrendous error.

This is the project:

#Region  Project Attributes 
    #MainFormWidth: 600
    #MainFormHeight: 400 
#End Region

Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.SetFormStyle("UNIFIED")
    'MainForm.RootPane.LoadLayout("Layout1") 'Load the layout file.
    MainForm.Show
End Sub

And these are the logs:

I wonder what can be happening

You need to use Java 8u40+ (Tools - Configure Paths).

Thank you, Erel. I had 8u91 but only in the JRE. I thought I was up to date in the JDK also. I installed 8u91 and I'm ready to play & learn.

While you are at it, and if you have an interest in hooking your B4A and B4i apps into a server with modern webapps, checkout the ABMaterial framework.
Without knowing diddly jack squat about B4J, I dove into ABM and learned a great deal about B4J at the same time.
However, I am still a dummy, just a lot less of one... ask anyone...

Best of luck and happy learning.
