Super rare NPE in AbstractPooledConnAdapter
-------------------------------------------
Key: HTTPCLIENT-1133
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1133
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient
Affects Versions: 4.1.1
Environment: Android. Using repackaged httpcore 4.1.1 in an app
obfuscated with Proguard.
Reporter: Michael Pujos
Priority: Minor
I've got 1 report of exception below:
java.lang.NullPointerException

Here's the line:
public HttpRoute getRoute() {
AbstractPoolEntry entry = getPoolEntry();
assertValid(entry);
return (entry.tracker == null) ? null : entry.tracker.toRoute(); //
<= NPE here
}
Looking briefly at the code and if the stack trace is legit (it seems to be),
the only possible cause of a NPE on this line
is if entry.tracker becomes null after the test entry.tracker == null happens.
It seems this could happen in the case the request is aborted and
AbstractPoolEntry.shutdownEntry() is
called in between, in another thread:
protected void shutdownEntry() {
tracker = null;
state = null;
}
