The following example demonstrates that the multi-release jar handling in JavacFileManager does not support paths to jars in non-default filesystems (in this case JimFS).

Disabling the multi-release jar handling by commenting out the line containing `--multi-release` allows the example to succeed.

=== Test.java
import com.google.common.jimfs.Jimfs;
import java.nio.file.FileSystem;
import java.nio.file.Files;
import java.nio.file.Path;
import java.util.Arrays;
import java.util.EnumSet;
import java.util.jar.JarEntry;
import java.util.jar.JarOutputStream;
import javax.tools.JavaCompiler;
import javax.tools.JavaFileObject;
import javax.tools.StandardJavaFileManager;
import javax.tools.StandardLocation;
import javax.tools.ToolProvider;

class Test {

  public static void main(String[] args) throws Exception {
    FileSystem fs = Jimfs.newFileSystem();
    Path foo = fs.getPath("/foo");
    Files.createDirectory(foo);
    Path hello = foo.resolve("hello.jar");
    try (JarOutputStream jos = new JarOutputStream(Files.newOutputStream(hello))) {
      jos.putNextEntry(new JarEntry("Test.class"));
      jos.write(Test.class.getClassLoader().getResourceAsStream("Test.class").readAllBytes());
    }

    JavaCompiler javacTask = ToolProvider.getSystemJavaCompiler();
    StandardJavaFileManager fileManager = javacTask.getStandardFileManager(null, null, null);

    fileManager.handleOption("--multi-release", Arrays.asList("8").iterator());
    fileManager.setLocationFromPaths(StandardLocation.PLATFORM_CLASS_PATH, Arrays.asList(hello));
    fileManager.list(
        StandardLocation.PLATFORM_CLASS_PATH, "", EnumSet.allOf(JavaFileObject.Kind.class), true);
  }
}
