Motivation: if tag is only created without any content then ResultSet#getBinaryStream return `null` as a stream which will trigger NPE. Modification: Update org.dcache.chimera.FsSqlDriver#getTag to check for null before accessing the stream. Result: NPE is fixed. Fixes: #8071 Acked-by: Dmitry Litvintsev Target: master, 11.2 Require-book: no Require-notes: yes (cherry picked from commit 6682eda) Signed-off-by: Tigran Mkrtchyan <tigran.mkrtchyan@desy.de>
