SecureQueryDecryptProcessor decode call could return null thus it  would get a NPE

We should look for decode return value and it is null should return :
UrlRewriteStepStatus.FAILURE instead of try to process return null value.

For example if encode fail you may get:

Failed to rewrite URL: https://edl-test-primary.bde-np.info53.com:8443/gateway/default/webhdfs/data/v1/webhdfs/v1/landing/incoming/bcaps/TEMPG_TBA_OAFAPV10_MSTR_APP_VER_PAYMENT_SCHEDULE/TEMPG_TBA_OAFAPV10_MSTR_APP_VER_PAYMENT_SCHEDULE.del?_=AAAACAAAABAAAACQPRSZG4oUO6HBLU0Jhgy7Uzxx1SqYAyMtiwpBg2BYbeQwuoeCCaT7ZuP98H1XYHAvnDtPEiWPSZ5E9L_wfgk8feUD1KRMNPtV4JcYs5HZQxV7DLNHJ2U4TS_3ozHHQIr92g0gUNH1wcLWVYwlEy5YKUC-tGKlMBBaJdlbvJ426hoLVfh4g3RuEG_-m3-DRu8nnoccpjeh3DsO1Z9S7zPfzXIl5lkLznfd, direction: IN, rule: WEBHDFS/webhdfs/inbound/datanode
