Cannot read bundled resources with hash in the filename

Trying to access a resource via class.getResourceAsStream() fails with NPE if the file name contains hash (#).

Example bundle code to verify the fault:

@Component(immediate = true)
public class ResourceReader
{
private static final Logger LOG = LogManager.getLogger();

@Activate
public void activate()

{ String fileNameWithoutHashes = "file_without_hash.txt"; logFileContent(fileNameWithoutHashes);String fileNameWithHashes = "file#with#hash.txt"; logFileContent(fileNameWithHashes); }

private void logFileContent(String resourceFileName)}}
{
InputStream stream = ResourceReader.class.getResourceAsStream("/" + resourceFileName);
try (BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(stream)))

{ LOG.info(bufferedReader.readLine()); }

catch (Exception e)

{ LOG.error("FAILURE: Could not read " + resourceFileName); }

}
}

Resource files located in bundle root:
/file_without_hash.txt - content irrelevant
/file#with#hash.txt - content irrelevant

Problem is seen in Karaf using Felix framework. Switching to Equinox made the problem disappear.
