Description
During startup, if the starter configuration file has a line:
load !{ant.home}/lib/*.jar
then all the jars in the directory
{ant.home}/lib are added to the classpath of the root loader. However a line such as:load !{ant.home}
/lib/ant*.jar
results in no jars being added to the root loader classpath.
The "globbing" implemented in org.codehaus.groovy.tools.LoaderConfiguration is violating the Rule of Least Surprise – in particular * is only being expanded if it is the first character of a path component. Either proper globbing shold be implemented or a switch to using regular expressions should be made.
Globbing is clearly easier here for the user, but Java does not have a standard globbing sub-system, it only has support for regular expressions. Obvious directions:
- Extract the code from Ant that does the path globbing and just use it or a variation of it.
- Transform the glob expression into a regular expression and then use regular expressions in the Java code.
- Extend the current code to implement globbin so that it works in a more expected way.
Given the string manipulation support in Java, 2 may be the best way forward.

I think that might work. I suggest you simply try it 
The "bug" was that in foo/ant*.jar the "foo/ant" was seen as parent directory, where it should have been "foo/" only. The stars itself are replaced by a regexp pattern... and we use replaceAll for this... so in theory it should do.
