Crowd load ALL groups to dropdown list - app freezes

crowd ver. 2.8.3
setup: Crowd has established connection (with read-only access) with LDAP.
LDAP has for this moment 102762 groups.

When I try to specify which groups should have access into my application as it's described here on the step of getting access to Groups tab crowd fails and logs shows me: java.lang.OutOfMemoryError: GC overhead limit exceeded

Maybe when the users list will be collected in small parts, maybe in lazy model then crowd will be able to be more managable.

Also when I try to find something into such list scrolling is not optimal way of working. I would expect matching on the base of typing eg. type 3 letters and we will show you top 10 most appropriate results.
