Parser 1.x (v1): Could not find definition on the classpath with dots in definition name

[frantuma]

When defined in a referenced external file, a definition containing dots in the name causes the parser to fail with error:

java.lang.RuntimeException: Could not find .. on the classpath
	at io.swagger.parser.util.ClasspathHelper.loadFileFromClasspath(

Please check the following specs to reproduce the error:

spec1 and referenced spec1

spec2 and referenced spec2

Note that with version 1.0.39 the error seems to be similar but different (check spec1 above)

This is related to v1, but possibly it also occurs in 2.0/master, to be checked
