It seems like Teiid designer is having an issue "creating data source" on Mac. The issue seems to be relating to special characters. In this particular case the actual path where the tmp file for the data source was created is "/var/folders/na/na5gfgpPGnuA9hfG8B99Hk++TI/Tmp/LocalJdbcConnectorTemplate6229433815076709154-ds.xml" but by the time JBoss tries to create it the "++" characters are replaced with spaces resulting in the exception below.
