Incorrect URL Encoding when Hexa-Decimal Characters are present

Jersey Client is encoding the url incorrectly when the hexa-decimal characters are present in it.

For Example:
When the URL has query parameter: str LIKE '%Desk%'
The Encoding done by the API is : str%20LIKE%20%27%Desk%25%27
Expected Encoding to be done is : str%20LIKE%20%27%25Desk%25%27

Note that %25 is missing before Desk in the encoding by the api.

Similar encoding issue is seen whenever the query param has substrings like %Ab , %Da, %De and other hexa decimal characters
