JShell API couldn't determine import info exactly with some spaces in the qualifier:

-> debug
-> import java . sql . * ;
import java . sql . * ;
Compiling: import java . sql . * ;
Kind: IMPORT -- import java.sql.*;

compileAndLoad [Unit(import java . sql . * ;)]
++setCompilationInfo() Snippet:ImportKey(import java . sql . * ;,SINGLE_TYPE_IMPORT_SUBKIND)#35-import java . sql . * ;
import java . sql . * ;
-- diags: []
setStatus() Snippet:ImportKey(import java . sql . * ;,SINGLE_TYPE_IMPORT_SUBKIND)#35-import java . sql . * ; - status: VALID
compileAndLoad ins = [Unit(import java . sql . * ;)] -- legit = [Unit(import java . sql . * ;)]
compileAndLoad [Unit(import java . sql . * ;)] -- deps: [] success: true

recordCompilation: Snippet:ImportKey(import java . sql . * ;,SINGLE_TYPE_IMPORT_SUBKIND)#35-import java . sql . * ; -- status VALID, unresolved []

It will be "Snippet:ImportKey(java.sql.*,TYPE_IMPORT_ON_DEMAND_SUBKIND)#35-import java . sql . * ; -- status VALID, unresolved []"

This issue affects the display of jshell tool.

-> import java . util . stream . DoubleStream; // determine as bad
-> IntStream.of(1)
| Expression value is: java.util.stream.IntPipeline$Head@2437c6dc

I don't know that what other is affected by this issue.
