the method jdk.jshell.SourceCodeAnalysis documentation not working

A DESCRIPTION OF THE PROBLEM :
The method jdk.jshell.SourceCodeAnalysis documentation(String input, int cursor, boolean computeJavadoc) returns empty list for jdk.jshell.JShell when another SourceCodeAnalysis is already used for documentation.

The problem is in the method jdk.shell.SourceCodeAnalysisImpl List<Path> findSources()

The first SourceCodeAnalysis opens file system and keeps it open.
The second SourceCodeAnalysis tries to open the file system and fails.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expected that JShell instances are independent and it is possible to use multiple JShell instances in the same application.

---------- BEGIN SOURCE ----------
import java.util.List;

import jdk.jshell.JShell;
import jdk.jshell.SourceCodeAnalysis.Documentation;

public class Test {

public static void main(String[] args) {

JShell jsh1 = JShell.create();
List<Documentation> docs1 = jsh1.sourceCodeAnalysis().documentation("String",
                6, false);

System.out.println(docs1.get(0).signature());

JShell jsh2 = JShell.create();
List<Documentation> docs2 = jsh2.sourceCodeAnalysis().documentation("String",
                6, false);

System.out.println(docs2);

}
}
