Hi all,

I have a very strange behaviour of my Xtext application.

It runs perfectly in Debian (buster), but in CentOS it raises error after some reloads (the number is random) of the page where you have the Web Editor it raises the exception listed at the bottom of this message.
So it stops working as expected, no syntax check no highlight until you restart tomcat9.

The other difference is that the CentOS server is accessed through a VPN.
The CentOS version is 3.10.0-1062.18.1.el7.x86_64

Thanks in advance,
Luca

there is no official support for guice 4.3 so its hard to tell what is happening ...
can you reproduce this with a repeatedly running unit test?
you could also try to log if the injector instance is different in the good/bad case


Need professional support for Xtext, Xpand, EMF?

Hello Christian,

thank you for the answer, I came back to guice 4.0 but nothing changed.
It is hard to put that stuff in a unit test as I need same O.S., same tomcat and so on.
I will try to log the instance, and I'll ket you know.
Best,
Luca

Thank you,

I tried with guice 4.0 and guice 3.0.
Same problem, maybe is because of coyote connector (tomcat) configuration?
Maybe because of https?
This is the fail PUT

[code]
"PUT /leitfeld/xtext-service/update?resource=4e9e09f6.lt HTTP/2.0" 500 10552/code]

i assume the put is a fllow up error.
unfortunarely i dont have any time to reproduce a example.
are you able to preproduce this with jetty?
did you try a different jvm on CentOS
