[jira] [Commented] (IGNITE-6356) Signed overflow when reading
partition greater than Short.MAX_VALUE
[ https://issues.apache.org/jira/browse/IGNITE-6356?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16162967#comment-16162967 ]
Alexey Goncharuk commented on IGNITE-6356:
------------------------------------------
The reason is the following code in GridDhtPartitionMap.java:
{code}
for (int i = 0; i < size; i++) {
int ordinal = in.readByte();
int part = in.readShort();
{code}
which leads to a negative parititon ID.
