[jira] [Commented] (NIFI-6673) Expression language multiply
operation doesn't check for overflow
[ https://issues.apache.org/jira/browse/NIFI-6673?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17115932#comment-17115932 ]
ASF subversion and git services commented on NIFI-6673:
-------------------------------------------------------
Commit 1ba8f76a44bdf6fb3a6af8c74e678dd7d21ad70b in nifi's branch refs/heads/master from Alessandro D'Armiento
[ https://gitbox.apache.org/repos/asf?p=nifi.git;h=1ba8f76 ]
NIFI-6673 MultiplyEvaluator throws an Arithmetic Exception in case of Long overflow.
TestQuery checks that Long overflow is detected and Double overflow is correctly promoted to POSITIVE_INFINITY or NEGATIVE_INFINITY
The behaviour change is reverted until further investigations.
The overflow behaviour is still enforced by unit tests and documented in the expression language doc
This closes #3739

> To reproduce the bug, create a FF with an attribute equals to Long.MAX, then multiply it by 2 to that attribute in a following UpdateAttribute processor. The property will overflow to a negative number without throwing any exception
