[CI] JdbcSqlSpecIT fails because of unknown NamedWriteable Processor #30014
Description
Original comment by @tlrx:
The test JdbcSqlSpecIT failed today on CI on master branch:
LINK REDACTED
It reproduces locally:
./gradlew :x-pack-elasticsearch:qa:sql:security:no-ssl:integTestRunner -Dtests.seed=C56C85CB596BD3AA -Dtests.class=org.elasticsearch.xpack.qa.sql.security.JdbcSqlSpecIT -Dtests.method="test {math.testMathATan2}" -Dtests.security.manager=true -Dtests.locale=sq -Dtests.timezone=Indian/Mayotte
Many tests methods failed but they seem to have the same original root cause:
Throwable LINK REDACTED: java.sql.SQLException: Server encountered an error [Unexpected failure decoding cursor]. [SqlIllegalArgumentException[Unexpected failure decoding cursor]; nested: IllegalArgumentException[Unknown NamedWriteable [org.elasticsearch.xpack.sql.expression.function.scalar.processor.runtime.Processor][mb]];
