---------------------------------------

             Summary: FindBugs: Methods may fail to close stream in core module
                 Key: IGNITE-9165
                 URL: https://issues.apache.org/jira/browse/IGNITE-9165
             Project: Ignite
          Issue Type: Bug
          Components: binary
    Affects Versions: 2.6
            Reporter: Nikolai Kulagin
            Assignee: Nikolai Kulagin
             Fix For: 2.7
         Attachments: findbugs-result-apache-ignite[ignite-core]_2018_08_02_12_38_02.html

The method creates an IO stream object, does not assign it to any fields, pass it to other methods that might close it, or return it, and does not appear to close the stream on all paths out of the method.  This may result in a file descriptor leak.

Example:

 
{code:java}
// GridCacheAbstractLoadTest#GridCacheAbstractLoadTest()

try {
 props.load(new FileReader(GridTestUtils.resolveIgnitePath(
 "modules/tests/config/cache-load.properties")));
}
catch (IOException e) {
 throw new RuntimeException(e);
}{code}
 
One of possible solutions:
{code:java}
try(Reader reader = new FileReader(GridTestUtils.resolveIgnitePath(
    "modules/tests/config/cache-load.properties"))) {
    props.load(reader);
}
catch (IOException e) {
    throw new RuntimeException(e);
}{code}
