STS hang-up when editing *.class files

[manuzi1]

Hi guys, i get the following error, when I am copying (or paste) a phrase from a domain class:

Before we can get any further, I'm going to need some more information:

1. What kind of project is this? Grails? Spring? Roo?
2. What kind of file are you working on? java, groovy, aspectj? Your title mentions .class file, but you can't really copy and paste to them (unless you are using a byte code editor) And class files are not domain classes.
3. Any errors in the Eclipse error log? Window -> Show view -> other -> Error log
4. Is this problem reproducible? Or did it only happen once?

1. It is a Grails project
2. I am working on groovy. Yes I mean .groovy in the domain class, sorry for that
   Well it is that: I have the definition (String one, String two, ...) the mapping and the constraints.
   When I mark something f.e. in the mapping for example: street sqlType: "VARCHAR2(132)", then make STRG+C or right click copy, sts is frozen.
3. I just did it. Made it frozen, and restarted STS. Here are the Error Logs:

Getting a lock required more than 10000 ms. There might be a synchronization problem in this callstack or just the build/dispose process of some components took too long!

4. It is reproducible.

Sorry...one more thing to ask. After the hang, can you run jps and then jstack on the command line? Paste the information here.

(jps gets all java process ids. jstack prints the full stack trace of a single java process.)
