Mikhail Titov created ARTEMIS-5662:
--------------------------------------
Summary: NegativeArraySizeException in StringSimpleStringPool's
constructor
Key: ARTEMIS-5662
URL: https://issues.apache.org/jira/browse/ARTEMIS-5662
Project: ActiveMQ Artemis
Issue Type: Bug
Affects Versions: 2.31.2, 2.43.0
Environment: openjdk version "21.0.8" 2025-07-15
Reporter: Mikhail Titov
Attachments: NegativeArraySizeException_ StringSimpleStringPool.tar
A bug was discovered as a result of fuzz-testing of SimpleString class methods:
NegativeArraySizeException is thrown when passing a capacity greater than 2^30
to the StringSimpleStringPool constructor.
I have created a standalone repro for this bug (attached archive). You can
reproduce it by running the following command:
{code:java}
java -cp .:jars/* NegativeArraySizeBug.java{code}
This bug does not pose a threat, but since the constructor is public, please
consider the possibility of handling this exception or adding information about
it to the documentation.
