[jira] [Created] (CAMEL-11672) Input stream infinitive loop
Zeljko Vukovic created CAMEL-11672:
--------------------------------------
Summary: Input stream infinitive loop
Key: CAMEL-11672
URL: https://issues.apache.org/jira/browse/CAMEL-11672
Project: Camel
Issue Type: Bug
Components: camel-http
Affects Versions: 2.12.4
Environment: IBM Websphere Liberty Core 17.0.0.1
IBM Websphere Liberty Core 17.0.0.2
Reporter: Zeljko Vukovic
Priority: Critical
Dear Camel team,
While working on one integration we found issue related to camel-http component when solution is deployed on IBM Liberty core.
Same issue is not reproducible on Jetty and Tomcat.
Issue is connected to the code in IOHelper and CachedOutputStream$WrappedInputStream
We are using version 2.12.4 but I can see that same code is used also in latest versions.
https://github.com/apache/camel/blob/camel-2.12.4/camel-core/src/main/java/org/apache/camel/util/IOHelper.java
Problematic part are lines 196, 198 and 204.
Basically stream reader which is used org.apache.camel.converter.stream.CachedOutputStream$WrappedInputStream is not returning -1 like response of read method if empty string is provided on input.
This is wrong by specification of InputReader interface.
// in the case there is input which is empty string
while ( -1 != n) {
…
int n = input.read(buffer); ---> this is never -1 if string is empty "" already 0 and we have infinitive loop !!!
}
For our use case we have applied change in IOHelper to check and directly cover if stream reader produce same (non-valid) response to not produce infinitive loop.
If any questions around reproducing issue please let me know
Best regards,
Zeljko
