We might need to use '/' instead of File.separatorChar.
See javadoc for Class#getResourceAsStream:
"
public InputStream getResourceAsStream(String name)
Finds a resource with a given name. The rules for searching
resources associated with a given class are implemented by the defining
class loader of the class. This method delegates to this object's class
loader. If this object was loaded by the bootstrap class loader, the
method delegates to ClassLoader.getSystemResourceAsStream(java.lang.String).
Before delegation, an absolute resource name is constructed from
the given resource name using this algorithm:
If the name begins with a '/' ('\u002f'), then the absolute
name of the resource is the portion of the name following the '/'.
Otherwise, the absolute name is of the following form:
modified_package_name/name
Where the modified_package_name is the package name of this
object with '/' substituted for '.' ('\u002e').
