title: JSON not reading escape symbols from DB
body: <p>So, I got values from DB <code>@Table</code> that contains column with String value and json in it. But as I try to map it with <code>ObjectMapper.writeValueAsString()</code> all i get is this (Also implying that those escape symbols as backward slashes are in a string):</p>
  
  <p><code>\"list\" [ \"key\":\"value\", ...  , \"key\":\"value\"] }</code></p>
  
  <p>It also appears that <code>@Entity</code> class have other fields as that table columns, but they seem to map okay, without escape symbols inside a String</p>
  
  <p>Any idea why that happens? Thanks in advance</p>
