Dave Brosius updated CASSANDRA-12569:
-------------------------------------
Priority: Trivial (was: Major)
> Null Dereference
> ----------------
>
> Key: CASSANDRA-12569
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12569
> Project: Cassandra
> Issue Type: Sub-task
> Reporter: Eduardo Aguinaga
> Priority: Trivial
>
> 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}
