generate cds file for springboot project,but core dump

[dreamlike_ocean lei]

Hi,Vladimir Kozlov
I hope this email finds you well. I am writing to express my gratitude for
your previous advice regarding the core dump issue in our Leyden EA
project. Unfortunately, despite following your recommendations, the problem
persists.
I have uploaded the generated file to this location（
https://github.com/dreamlike-ocean/leydenPlayground/blob/master/hs_err_pid52915_disable_ReduceAllocationMerges.log）.
Could you please take a look and provide further guidance on resolving this
issue?

Thank you in advance for your assistance.

Best regards, Dreamlike
