gpadbidri opened a new issue, #6318:
URL: https://github.com/apache/incubator-kie-drools/issues/6318
We’re using Drools with Spring Boot and encountering an "Unexpected Global"
exception under inconsistent conditions.
The same rule behaves differently across different inputs — it works for
some executions and fails with this exception for others. We're unable to
identify a consistent pattern for when the global is accepted vs when it's
rejected.
Environment:
Drools version: 8.41.0.Final
Spring Boot version: (please include if known)
Maven dependency:
<dependency>
<groupId>org.drools</groupId>
<artifactId>drools-mvel</artifactId>
<version>8.41.0.Final</version>
</dependency>
Symptoms:
We dynamically assign globals before inserting facts and firing rules.
Example code:
`references.forEach((key, value) -> {
try {
session.setGlobal(key, value);
} catch (Exception e) {
log.error("Failed to set global: {}", key, e);
}
});
`
The error only occurs for some executions, even when using the same rule and
same code path.
Question:
What could cause a global to be accepted in some cases and throw Unexpected
Global in others? Could it be due to rule compilation caching, or something in
how the session or globals are initialized?
