Subject	Details
Rector version	Rector dev-master@765862c
Installed as	composer dependency

I want to replace snake_case to cameCase in all my code.
When I run rector with the configuration below (see the link), it somehow changes PHPDoc annotation, but there is no rule which indicates these changes.

Minimal PHP Code Causing Issue

Expected Behaviour

     public function showAction(Request $request, $id)
     {
-        $invoice_service = $this->get(InvoiceService::class);
-        $current_user = $this->get('security.token_storage')->getToken()->getUser();
+        $invoiceService = $this->get(InvoiceService::class);
+        $currentUser = $this->get('security.token_storage')->getToken()->getUser();
     }
 }

Actual Behaviour

class InvoiceAdminController
{
    /**
-    * @Route("/admin/invoice/show/{id}", options={ "expose" = true }, name="invoice_admin_show")
+    * @Route("/admin/invoice/show/{id}", options={expose=true}, name="invoice_admin_show")
     *
     * @param mixed $id
     */
    public function showAction(Request $request, $id)
    {
-        $invoice_service = $this->get(InvoiceService::class);
-        $current_user = $this->get('security.token_storage')->getToken()->getUser();
+        $invoiceService = $this->get(InvoiceService::class);
+        $currentUser = $this->get('security.token_storage')->getToken()->getUser();
    }
