Andy Seaborne commented on JENA-1936:
-------------------------------------
The behaviour illustrated above would explain it; where n1 is the data node and
n2 the pattern node, it doesn't match for graphmem. Presumably "a0" did not
work.
Note the "wellformed" at
https://github.com/apache/jena/blob/master/jena-core/src/main/java/org/apache/jena/graph/impl/LiteralLabelImpl.java#L311
which explains "A" working. But the fix would be elsewhere, maybe according to
the TODO at line 308 in some way, but that may be too large if done for all
datatypes.
And the command line does not use graphmem these days.
