question about primitive chars

All

I have an external Java compiled lib whose public interface method expects a primitive char arg.

Does groovy (and am using grails here, 1.2M2 - though shouldn't matter) not autobox for such methods? All my efforts to try to get this method called from my groovy code are failing. No amount of toCharacter().toChar() or other approaches is yielding any success. My tests are failing because the signature expected on the external lib is not one which matches the args I am generating -

groovy.lang.MissingMethodException: No signature of method:
net.sf.flatpack.DefaultParserFactory.newDelimitedParser() is applicable
for argument types: (java.io.BufferedReader, java.io.BufferedReader,
java.lang.Character, null, java.lang.Boolean) values:
[java.io.BufferedReader@5cee644c, java.io.BufferedReader@26fae93e, |,
null, false]

Any suggetions?

http://flatpack.sourceforge.net/apidocs/net/sf/flatpack/DefaultParserFactory.html

newDelimitedParser(java.io.InputStream pzmapXMLStream, java.io.InputStream dataSourceStream, char delimiter, char qualifier, boolean ignoreFirstRecord)

I've been scanning the API and these guys are using char everywhere.. Asides from the problem this is causing my groovy dev, what bites about using char is the inability to specify a null value... sigh

I pasted the wrong method, they have a Reader enabled method

http://flatpack.sourceforge.net/apidocs/net/sf/flatpack/DefaultParserFactory.html#newDelimitedParser%28java.io.Reader,%20java.io.Reader,%20char,%20char,%20boolean%29

When i used

"," as char

that seemed to fix it.. took me a while to find an example online from someone else
