into d8be9eb on mybatis:master.

[harawata]

Merged.
Make sure not to create a vulnerable implementation.

[brucelwl]

Can we also merge this code in version 3.5.20 ?

[harawata]

Only critical issues will be fixed in 3.5.x, I think.

[brucelwl]

This is a small change, If mybatis 3.6.x no longer supports Java8, I think it is still necessary to merge the code to version 3.5.x. If 3.6.x continues to support Java8, that would be acceptable

[harawata]

This is a minor change that is irrelevant to most of the users, so no, we will not release 3.5.20 for this.
I hope you understand.

[brucelwl]

I am not saying that release version 3.5.20 specifically for this small change, but I hope that this change can be carried when we release version 3.5.20 in the future
