Does the framework support introducing a third jar in the enclave?

Hello, there are two framework issues:
1. Does the framework support introducing a third jar in the enclave? For example, in MOCK_N_JVM mode, referencing Alibaba Fastjson 2 can be used, but there is an error when compiling in TEE_SDK mode. Do you have any use cases?
Error:
Classes that should be initialized at run time got initialized during image building: com.aliabba.fastjon2.JSONObject was unintentionally initialized at build time.

2. Secondly, does the Service in the enclave support Java8 functional programming, where lambda expressions are passed as parameters to the encryption module for execution?
