generate cds file for springboot project,but core dump

[Vladimir Kozlov]

Hi, Dreamlike

I reproduced reported issues locally and found fixes.
I filed two bugs [1] for mainline and sent PRs with suggested fixes.
It will take time to include fixes and re-spinning Leyden EA release.
We let community know when we update Leyden EA.

Thank you again for trying Leyden EA release and reporting issues.

Regards,
Vladimir K

And Leyden specific bug to track all these issues:
