Solve by the steps:

1. copy the start.sh from dubbo to a individual place
2. change the -Xss to 512K in start.sh
3. start the system and it seems ok

Does the -Xss=256K is too small ? So not all the Beans can be loaded by the JVM?
So I wonder if -Xss is a configurable option?

Thanks for your report, I think the stack space should be bigger in the Spring scenario.
