Peter Somogyi commented on HBASE-20180:
---------------------------------------
nit: Don't add the 2 extra lines in CoprocessorHost.
Class:newInstance left in code:
* TableSnapshotInputFormatImpl:305
* MultithreadedTableMapper:284
> Avoid Class::newInstance

> Class::newInstance is deprecated starting in Java 9 -
> https://bugs.openjdk.java.net/browse/JDK-6850612 - because it may throw
> undeclared checked exceptions. The suggested replacement is
> {{getDeclaredConstructor().newInstance()}}, which will wrap the checked
> exceptions in InvocationException.
> There's even an error-prone warning about it, we should promote that to error
> while we're fixing this.
