Yes, you can use
META-INF/serviceswithout a jar file. At least that’s what happens according to my test (Java 6).The
META-INFdirectory of all jar files and all directories in the classpath can be scanned independently, so technically such aMETA-INFfile doesn’t override the file from another jar file, but (depending on the loader mechanism) entries in one of the files (resource of one of the class loaders) may have priority over other files, so in fact you can overload entries. As you already found out, one such case isjavax.xml.datatype.FactoryFinder(I didn’t know that).
