Changes on .xtend file crashes the workspace [message #1706575]

Hi all,

I am quite confused. I've implemented a DSL some time ago and
customized the generated xtext modules. Now I want to add some
small changes to the .xtend classes (docu...) but I can't save any .xtend file.

After I start typing the whole workspace freezes and I have to terminate the 'java.exe' process by hand.

I am using 'Eclipse Luna DSL' ( Luna Service Release 1 (4.4.1)) with
the following plugins:

https://dl.dropboxusercontent.com/u/18688378/eclipseCoding/errors/xtend/usedPlugins.JPG

My eclipse.ini file looks like this:

-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20140603-1326
-product
org.eclipse.epp.package.dsl.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
2048m
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
2048m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Xms256m
-Xmx2048m

Any suggstions welcome!

PS: I've changed the .xtend files with an simple text-editor and added them back to eclipse, the buildmechanism from xtend -> java works, but I'm not able to used the xtend-editor..

does this happen in a specific projects or in a projects? does it happen in a fresh workspace using the same projects as well? does it freeze forever or does it recover after some minutes?

Hi,

I've just tried it out ... in a fresh workspace (old projects) it works fine..
In the old "buggy" workspace it crashes AND the generated DSL-Editor (of my own dsl) in an eclipse runtime was really slow...

Any idea what might be the reason?

nope. you would have to remote debug to find out what happens. deadlock or infinite loop

A little question about the slow editor, my serailized dsl-AST is about 1000 lines big. But the usage of the editor is nearly impossible. every letter appears after 1/2 sec....

My DSL is an expression language with a underlining type-system that instantly performs a live-validation. the "normal" validation covers about ~70 validation rules.
I also use a customized index (with some data in the user-data map) and perform some manuel linking for a view elements.

might this be a problem/reason for the really slow behaviour of the generated editor?
