-------------------------------------------------------
Commit 1a3f662f31533700685eda774458eba9a6766229 in jena's branch
refs/heads/master from [~rvesse]
[ https://git-wip-us.apache.org/repos/asf?p=jena.git;h=1a3f662 ]
Remove unecessarily strict check in BuilderTable (JENA-1566)
Check prevents valid node values being parsed for row entries and there
is already checking of invalid values that happens after the attempt to
parse the node value. Adds various unit tests around BuilderTable as
well.

> As a bit of background, we are trying to rewrite SPARQL queries using ARQ in
> Clojure (as described in JENA-1468). The current process is:
> Parse SPARQL query -> Compile to Op -> serialise to string -> parse as SSE ->
> modify SSE -> serialise to string -> Parse to Op -> convert to SPARQL query
> This issue is causing the 'parse as SSE' step to fail.
