Jared Stewart created GEODE-2796:
------------------------------------
Summary: 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
It looks like an NPE was introduced by the fix for GEODE-2290:
{noformat}
Caused by: java.lang.NullPointerException

{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).
