libxml2 not supported by this version

After upgrading (past upgrades all no problem) from 10.0.15 to 10.0.17 several "CREATE table" with ENGINE=CONNECT table_type=XML fail.
This happens with XML files that have ":" in the attributes, like for example: <Test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"></Test>
When trying to use option_list='xmlsup=LIBXML2' one gets SQL Error (1105): libxml2 not supported by this version.
If option_list='xmlsup=DOMDOC' then SQL Error (1296): Got error 174 'Loading of /test.xml failed' from CONNECT.
On version 10.0.15 was working OK without xmlsup option definition.
Now even copying over all the .exe, etc files to previous version (but maitaining the data) keeps the same problem.
Strangely all versions now report in the boot log: CONNECT: Version 1.03.0006 Jan 25 2015 07:43:28 while the MariaDB website says the latest version as of today is 1.03.0005 !
This blocked all my projects. Hope a good soul can check this issue.
