Servoy Developer HANGS after showing Welcome page.

Postby pbdavis » Thu Nov 30, 2017 6:01 pm

Installed version of 8.2.1 using Default settings on MacBook Pro running macOS Sierra 10.12.6. Installed JDK 8u152. BTW, I have Eclipse Neon.2 working just fine. After starting the Servoy Developer the Welcome page load then Sevory completely hangs. Nothing is selectable. I have to force quit to close Servoy. I have a proxy that must be used to get to the internet (i.e., company LAN). I have tried different settings in OS X and in the Java Preferences to set the proxy. I've tried uninstalling and re-downloading and another install. Same problem. Any ideas on why Servoy Developer is hanging on startup?

on an empty workspace?
That is quite strange, what you can do is go to the localhost:8080/servoy-amdin page in your browser when the developer hangs
And then make a stack dump so we can see what it is doing

I had exactly the same problem (see discussion here viewtopic.php?f=11&t=21967). Nothing worked until I completely reinstalled Mac OS on a new partition. I suspect the problem is with Java 8 conflicting somehow with Java 6 that you cannot remove because Servoy needs it to run.

this is not true, Servoy does not need java6, the latest Servoy versions of 8.x even don't run on Java 6...
the "need" for this is a configuration error on the mac as far as i can remember

Yes, it is a while since Developer needed Java 6.
There was a time you had to manually edit some setting to use a more recent Java.
I think this is an unmodified install of 8.2.x
But, maybe I should update my JDK...

I have no doubts that Servoy 8 doesn't run on Java 6, but when I installed 8.2.1 it refused to work unless java 6 virtual machine wasn't installed on my Mac. See also this discussion https://forum.servoy.com/viewtopic.php?f=11&t=21967

i know but way back i think Servoy World 2 years ago
There where people complaining exactly what you are saying, and when i looked at that it was really just a problem of there system, there is something not installed correctly
this is because the default Oracle install doesn't set everything right. i can't remember exactly what it was anymore, people that really have and use OSX should jump in.

I think this is the way the eclipse.app wants to lookup the jvm, and it will not find one even if Oracles is installled and because of that it asked for the latest apple itself shipped (and that was i think java6)

ISSUE FIXED!
Uninstalled JDK version jdk1.8.0_152.jdk. The other version I had already installed, jdk1.8.0_121.jdk, works with Servoy Developer. Servoy Version 8.2.1 is now working on macOS Sierra 10.12.6.

Hi,

now I've the same problem ... since macOS High Sierra 10.13.6 Update my Servoy Developer hangs after showing Welcome Page.
Hang on is after loading about 30 %.
I've reinstalled Servoy Developer and tried different JDK Versions, but no success.
Servoy Version 8.3.0, JDK Version 151,macOS High Sierra 10.13.6.
Is it possible to track Servoy Developer startup? Is there a Startup-log-File available?

it could be that a log file is created here: developer\configuration

else it is only in the .metaspace of your workspace where eclipse logs its standard stuff

Maybe if you start through the command line you can see a bit more,
or maybe you can connect to it with jvsualvm to see what it is doing by looking at the thread stack dumps

there is no log file created.
workspace itself seams to be ok, because I've installed SERVOY 8.3 on a virtual windows 10 machine and the workspace runs very well.
has anyone Servoy 8.3.0 on macOS High Sierra 10.13.6 installed and no problem?
which JDK Version is used?
or does anyone have any other solution?

I have had this issue in the past as well, if I remember correctly the solution for me was to reboot after upgrading Java. More recently I had issues with solutions not running on client machines with a java runtime higher than Java 8 update 161 which would result in a unresponsive security dialog and a hanging Java console. I suspect my developer had been upgraded from older versions so many times that it was burdened with previous properties and or settings, so a fresh install of Servoy 8 and importing and rebuilding the solution on that did the trick. I also got less security warnings after that.
