A number of the Geronimo specs use the provider resolution pattern defined by the ServiceLoader class in Java 6 to resolve different provider classes. In this pattern, a file with a given class name in the META-INF/services directory can define one or more provider classes for a given source interface name. As implemented by the ServiceLoader class, these files can contain multiple lines with pure comment lines and line comments on lines that define classes, as well as multiple providers defined per file. Thus a file like this would be considered valiid:
- A set of provider classes for the blah.blah interface
org.apache.geronimo.foo.BlahImpl # The default first one
org.apache.geronimo.bar.BlahImpl # The secondary fall back.
The different spec projects that use these files parse them under different assumptions:
- Some unilaterally take the first line without any comment processing at all or recognition that there might be multiple providers defined per file.
- Some projects allow for pure comment lines but don't parse for comments on a definition line.
- Not all projects are opening these files assuming a utf-8 encoding.
This could best be solved by refactoring the code to use some common methods. This refactoring will also allow OSGi-awareness to be added to the service file lookups.
