I20060125-0800 Startup on my machine became very slow. Each time I do a stack dump it looks like sitting waiting for some preference in AbstractVMInstall.evaluateSystemProperties(...). This might be related to bug .

Wassim, do you think we can cache EE info (or perhaps system property info)?
Caching certainly seems like a good idea. It may be easier for you to cache the system properties retrieved rather than an EE classification by an analyzer. If you choose to persist how each VM is analyzed, you would have to keep track of all analyzers, their analysis of a VM and you would also have to become dynamically aware. So caching system properties for a VM is enough and won't require Excedrin :-)
The hang has been fixed by a re-work for bug 124137. We still may want to cache system properties, however, I will open a new bug for that. *** This bug has been marked as a duplicate of 124137 ***
