Currently there is no resolution.
As workaround, the share will need to be mounted with "vers=3", then re-bind apps to the new mount. Valid values are 3, 4.0, 4.1 or 4.2. See
TAS documentation.
cf create-service nfs Existing SERVICE-INSTANCE-NAME -c ‘{“share”:“SERVER/SHARE”, “version”:“NFS-PROTOCOL”}’
