STS very slow in building workspace. "Loading *-context.xml". Network activity

OK, it's attached as jstack.txt.

Great, thanks!!!

Obviously, a fix would be great, but I'm desperate for any kind of workaround. What could I disable to stop this from happening?

[Martin Lippert]

Hey!

You can remove the Spring project nature, that could be a workaround, but it is the rather aggressive version of a workaround... ;-) I am working on a fix for this. Please attach some more thread-dumps to the bug in JIRA if you come across this issue. And maybe a full sample project would also be of great help for this!!!

Hey,

I just found that when I open the this *-context.xml in STS with Spring Config Editor and disable context in Namespaces tab the problem goes away... My question is how can this affect developing? I have configured VMware vFabric tc Server to have hot swap. Does this turning off the context in namespaces can cause any problems?

Thanks in advance.

Hey!

You mean when you disable the context namespace in the Namespaces tab of an spring-config.xml file? That means that you did't use the "context" namespace in your config xml, but you had declared it and that slowed it down?

Hey,

This are my first steps with STS so after I disabled this context namespace in spring-config.xml my application didn't start up so i had to add it back I was thinking that is not editor for this file. I was thinking this is some validator setting. After searching in google for some solution I just turned off Spring builder (didn't turn off nature) and it works well for me. I've found no other satisfying solution.

Hey!

Ah, okay, good to know and thanks for the update. Is there any chance to get a sample projects that behaves so slow on your end? I really would love to see this slowdown on my end as well in order to find out what exactly causes this issue.

Thanks for your help!

I've solved the issue by removing all "Config Files" in the Spring "Beans Support" in the project properties.
In case of Web Application, I had to disable Config Detection.(see attached image.)
You might need to enable it only when you are working on Spring configurations.

Hey!

Can you capture a few thread dumps for us while STS slows down to dramatically when having those config files configured there? I hope that we can figure out what is going wrong with this in order to fix the root cause of this. Capturing some thread dumps is easy using jps and jstack while STS is slow. Would help us a lot!!!

Thanks!
