[MONDRIAN-2038] - Data Source (Wizard) returning  java SQLDataException:...

... ORA-01861: literal does not match format string.

added attempt of parsing string to TimeStamp if it isn't Date
removed quoteDateLiteral() from AccessDialect - it is the same as it's parent now
Sorry I didn't see that before, but the Pattern must be precompiled as a static variable of that class. Compiling it costs a lot of processing so we only compile it once and re-use it to match when needed.
