[ https://issues.apache.org/jira/browse/GEODE-2796?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jared Stewart updated GEODE-2796:
---------------------------------
Fix Version/s: 1.2.0
> NPE in ClassPathLoader
> ----------------------
>
> Key: GEODE-2796
> URL: https://issues.apache.org/jira/browse/GEODE-2796
> Project: Geode
> Issue Type: Bug
> Components: management
> Reporter: Jared Stewart
> Assignee: Jared Stewart
> Fix For: 1.2.0
>
>
> It looks like an NPE was introduced by the fix for GEODE-2290:
> {noformat}
> Caused by: java.lang.NullPointerException
> at org.apache.geode.internal.ClassPathLoader.getResource(ClassPathLoader.java:130)
> at org.apache.geode.internal.ClassPathLoader.getResourceAsStream(ClassPathLoader.java:239)
> at org.apache.geode.internal.ClassPathLoader.getResourceAsStream(ClassPathLoader.java:264)
> at org.apache.geode.internal.GemFireVersion$VersionDescription.<init>(GemFireVersion.java:191)
> at org.apache.geode.internal.GemFireVersion.getDescription(GemFireVersion.java:52)
> at org.apache.geode.internal.GemFireVersion.getGemFireVersion(GemFireVersion.java:66)
> at org.apache.geode.cache.CacheFactory.getVersion(CacheFactory.java:305)
> ...
> {noformat}
> This is caused by the following method:
> {noformat}
> private List<ClassLoader> getClassLoaders() {
> ArrayList<ClassLoader> classLoaders = new ArrayList<>();
> if (!excludeTCCL) {
> classLoaders.add(Thread.currentThread().getContextClassLoader());
> }
> classLoaders.add(classLoaderForDeployedJars);
> return classLoaders;
> }
> {noformat}
> According to the JavaDocs, `getContextClassLoader()` actually returns null to indicate the system class loader (rather than actually returning the system class loader).
