We should update our installation guide for EAP5 (especially the part for Windows on page 6). We recommend to set JAVA_HOME variable to C:\Program Files\Java\jdk1.6.0_<latest_update>\ and also to add C:\Program Files\Java\jdk1.6.0_<latest_update>\jre\bin to PATH variable. I used these settings and I have problems with starting the server (server ends up with ClassNotFoundException - see linked issue).

We should warn users and customers to be careful and not install Java to directories which contain spaces in their names and also we should warn them not to use directories with spaces in PATH environment variable on Windows, because they may have problems with starting the server.

Problem is probably in starting script (run.bat) which can not process correctly directories with spaces in PATH environment variable.
