Addition of toString() method to document class results in it not being located
starksm64 opened this issue · comments
I have a document class that was not being picked up during the JsonDBTemplate initialize phase. After stripping it down to determine what might be causing it, I found that just the inclusion of the public String toString()...
method in the class was causing it to not be recognized as a valid collection. I have not looked into why that is.
I did track it down to this problem:

This is due to an older version of javassist being included by a parent project. Updating javassist fixed the issue.
