Bouncycastle class error using Alfresco CE 5.2

[egobsv]

Hi, here is the error I am getting on the browser, no error gets logged on alfresco.log nor catalina.out. Should I be using CE 5.1 instead?

{"status" :
{
"code" : 500,
"name" : "Internal Error",
"description" : "An error inside the HTTP server which prevented it from fulfilling the request."
},
"message" : "com.itextpdf.text.ExceptionConverter: class "org.bouncycastle.asn1.DEREncodable"'s signer information does not match signer information of other classes in the same package",
"exception" : "",
"callstack" : [ ],
"server" : "Community v5.2.0 (re21f2be5-b22) schema 10,057",
"time" : "Sep 26, 2017 2:27:09 PM"
}

What does it do when you try the current version of CE 201707 ?
