Description _ rkubacki 2004-10-13 14:06:39 UTC 
j2seplatform module reads user properties file and
definition of platforms to check if Java
specification version matches to version of javac
source and target settings. This is pretty
expensive operations that takes ~450 ms from 20s
of startup time on my machine (Dell notebook
P4/2GHz/1GB RAM, linux 2.4.8, JDK1.5.0).
Comment 1 _ rkubacki 2004-10-13 14:10:45 UTC 
possible improvement is to avoid resolving of DTD and supply empty
content instead of stream with DTD. This save 20-30% of module install
time thought I am not sure what part is looking for default entity
resolver and what is the reading of DTD.

We can also avoid computing of display name of platform in constructor.
