--------------------------------------------------------------
KB and CDI model use data from jars, so that they are loaded at first request. 
If there are dependencies between projects in workspace then a request from one 
project loads all related projects. There should be only one *JarAccess* object 
for a jar. If several projects use the same Maven dependencies and/or Runtime, 
they should use same *JarAccess* object for each jar. Now, a new Java EE Web 
project created from JBoss Central has in Maven Dependences and JBoss AS 7.1 
Runtime 170 jars. So, it is probable that your workspace does reference 900 or 
more distinct jars. Could you please check that. If the number of distinct jars 
in your workspace is much less, than there is a memory leak with JarAccess. 
Instances of *JarSystemImpl* are created for each jar in each project, but they 
are sharing data if they reference the same jar, so that if there are 6.044 
Instances of *JarSystemImpl* but only 900 distinct jar files, then only 900 of 
*JarSystemImpl* instances will be loaded, the other will be lightweight 
references to them. These objects are lazy-loaded that is they load only as 
much data as requested. However, KB builder now  searches through the entire 
jar for files myfaces-metadata.xml and facelet taglib files; and in this way 
results in complete loading of data which cannot be easily released being 
shared between projects. So, I think that we have to check if we can avoid 
scanning through the entire jar.
