Problem description

Calling a method with 10 parameters. Getting this error when setting the 8th.

com.microsoft.sqlserver.jdbc.SQLServerException: The index 11 is out of range.

I've located the problem occurs when a method calls findColumn(parameterName) multiple times.
the problem is inside private int findColumn(String columnName)

map.putIfAbsent(columnName, ai.incrementAndGet());
return map.get(columnName);// attempting to look up the first column will return no access exception

The ai.incrementAndGet() is called even though the parameter is already present.
This is fine if there are no more parameters after it, but there are this time.
suggested correction:

return map.computeIfAbsent(columnName, ignored -> ai.incrementAndGet());

Hi @coladict, thanks for bringing this to our attention. Currently we're busy preparing for release, would it be possible for you to open a PR? Or could you provide us a repro that we can use for a test? If not we'll try and address this as soon as we can.
