------------------------------------------
Summary: BinaryStream position integer overflow
Key: IGNITE-6636
URL:
https://issues.apache.org/jira/browse/IGNITE-6636 Project: Ignite
Issue Type: Bug
Security Level: Public (Viewable by anyone)
Components: general
Affects Versions: 2.2
Reporter: Alexandr Kuramshin
There were some issues with negative {{BinaryAbstractStream#pos}} value.
We may get stack trace like that
{noformat}
java.lang.ArrayIndexOutOfBoundsException: -2142240123
at org.apache.ignite.internal.binary.streams.BinaryHeapOutputStream.writeByteAndShift(BinaryHeapOutputStream.java)
at org.apache.ignite.internal.binary.streams.BinaryAbstractOutputStream.writeByte(BinaryAbstractOutputStream.java)
at org.apache.ignite.internal.binary.BinaryWriterExImpl.marshal0(BinaryWriterExImpl.java)
at org.apache.ignite.internal.binary.BinaryWriterExImpl.marshal(BinaryWriterExImpl.java)
{noformat}
The worst of it is that the {{ArrayIndexOutOfBoundsException}} has been thrown on the next write to the stream, and upon stack unwinding we couldn't know which object actually cause the overflow.
I've to suggest to check all updates to the {{BinaryAbstractStream#pos}} and throw exception right after the change.
