Hot deploy not longer working -- fails at most simple statement

[anon137564]

Hello!

I've got a really annoying problem with my JBoss AS 4.2.3.GA. Until recently everything was working fine but now hot deploy is not longer working.

My IDE is Eclipse and I'm using Maven. I have freshly cleaned, installed and deployed every project that is running on my server. When I now just add a single statement like System.out.println("test"); to one of my method's bodies, Eclipse prompts the error message "Hot code replace failed - Scheme change not implemented".

Here is a little screenshot of the error prompt:

As always I don't know what I've done for the error to occur. I hope you have some hints for me regarding the solution of this annoyance.

Thank you

Guy

I did the following things now that ultimately lead to the solution of the problem.

1. Uninstall all JDKs and JREs
2. Install JDK5 (that's the one we use in  production)
3. Clean, install and deploy every project anew

Now hot deploy seems to work again. I've used JDK 6 Update 20 in Eclipse and Update 7 in Maven. Maybe that has caused the inconsistency between their two builds.
