Now that Glenn seems to have got past the issue by following the
workaround suggested, do you think we should fix this code, to handle
the case where the module name could have a slash character. I think the
fix could be as simple as:
diff --git a/src/main/org/apache/tools/ant/types/CommandlineJava.java
b/src/main/org/apache/tools/ant/types/CommandlineJava.java

Just like you, I'm not fully sure why that executableType == null check
is there. Maybe that whole if/else block along with the switch is trying
to take into account the case of attribute order parsing (for example,
the "classname" attribute having been parsed before the "module"
attribute because that's how the user used it?) while reading the
"<java>" element?
