I think there is a very big classloading performance issue with
extensibility-osgi. Running itest/osgi-tuscany/osgi-tuscany-test takes three
times as much time using the ServiceDiscoverer in extensibility-osgi
compared to using the standard Classloader based ServiceDiscoverer using the
BundleClassloader as we used to.
With the current build of Tuscany on my thinkpad:
Using extensibility-osgi
[INFO] Apache Tuscany OSGi-Based Tuscany Runtime Tests ....... SUCCESS
[14:09.609s]
The same build without extensibility-osgi (with BundleClassloader as TCCL)
[INFO] Apache Tuscany OSGi-Based Tuscany Runtime Tests ....... SUCCESS
[3:54.796s]
These figures show around 10 minutes extra execution time, attributed purely
to classloading differences. Even though these tests show a worst-case
scenario since there is an awful lot of classloading going on here with
Tuscany being loaded many times, I think we should address this because the
impact is significant.
Thank you...
