--------------------------------------------
Summary: Null Dereference
Key: CASSANDRA-12569
URL: https://issues.apache.org/jira/browse/CASSANDRA-12569
Project: Cassandra
Issue Type: Sub-task
Reporter: Eduardo Aguinaga
Overview:
In May through June of 2016 a static analysis was performed on version 3.0.5 of
the Cassandra source code. The analysis included an automated analysis using HP
Fortify v4.21 SCA and a manual analysis utilizing SciTools Understand v4. The
results of that analysis includes the issue below.
Issue:
In the file SnitchProperties.java on line 48 the call to getResource and
getClassLoader may both return a null, which would cause a null dereference.
{code:java}
SnitchProperties.java, lines 40-59:
40 try
41 {
42 URL url;
43 if (configURL == null)
44 url =
SnitchProperties.class.getClassLoader().getResource(RACKDC_PROPERTY_FILENAME);
45 else
46 url = new URL(configURL);
47
48 stream = url.openStream(); // catch block handles potential NPE
49 properties.load(stream);
50 }
51 catch (Exception e)
52 {
53 // do not throw exception here, just consider this an incomplete or an
empty property file.
54 logger.warn("Unable to read {}", ((configURL != null) ? configURL :
RACKDC_PROPERTY_FILENAME));
55 }
56 finally
57 {
58 FileUtils.closeQuietly(stream);
59 }
{code}
