----------------------------------------
Summary: File stream cache problem with multicast parallel
processing and encrypted stream
Key: CAMEL-16177
URL: https://issues.apache.org/jira/browse/CAMEL-16177
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 3.7.2
Reporter: Franz Forsthofer
Fix For: 3.7.3, 3.8.0
If you use stream caching with file encryption in a camel route where you have
a multicast with several branches, then it the following errors can happen in
the message processing of the branch.
* When the message is processed in a branch you can get the following
exception:aused by: java.lang.ArrayIndexOutOfBoundsException: while trying to
load from index 16 of a byte (or boolean) array with length 16, loaded from
field com.sun.crypto.provider.CounterMode.encryptedCounter of an object loaded
from local variable 'this'aused by: java.lang.ArrayIndexOutOfBoundsException:

org.apache.camel.converter.stream.FileInputStreamCache.read(FileInputStreamCache.java:139)
* or you get a damaged payload in the branch which is not correctly decrypted
The root cause of the problem is that the decryptor is not thread safe: If two
different FileInputStreamCache instances use the same decryptor in two
different threads at the same time, the above problems occur.
I will provide a patch for this problem.
