Make sagas work with devTools

[cer]

Problem:

• devtools uses it's own classloader
• eventuate libraries use a different classloader
• DevTools can cause errors such as java.lang.ClassCastException: class X cannot be cast to class X - X and X are from different class loaders

This is the likely solution: https://github.com/spring-projects/spring-boot/issues/3805

Eventuate libraries (including JSonMapper) need to use ThreadLocal.getThread().getContextClassLoader()

@cer Chris, could you please clarify, should I jast replace explicit classloader usage by ThreadLocal.getThread().getContextClassLoader(), or there is something else?

Btw, I found only these entries:

https://github.com/eventuate-foundation/eventuate-common/blob/master/eventuate-common-json-mapper/src/main/java/io/eventuate/common/json/mapper/JSonMapper.java#L43

AFAIK as I know that's all that's required. I'd first try to reproduce the problem by including Devtools and then verify that the change fixes the problem.

Got it, thank you
