Jan Bednar commented on CAMEL-14299:
------------------------------------
I can reproduce this with your code. The datasource is auto configured with
spring boot. During this initialization there are some calls to openConnection,
which causes HikariConfig to seal. Then comes in place Camel Introspection
trying to set DataSource to HikariConfig object, which is already sealed and
cannot be modified.
Until we find solution, you can use one of these workarounds:
Replace *toD* with *to* and *CamelSqlQuery* header
{code:java}
.setHeader("insertSql", constant("insert into tmp (col1, col2) values
(:?val1, :?val2)")) //Notice ? instead of #
.setHeader("CamelSqlQuery", header("insertSql"))
.to("sql:insert?dataSource=#dataSource")
{code}
OR downgrade hikari in your pom to lower version , where sealing mechanism was
not implemented
{code:java}
<dependency>
<groupId>com.zaxxer</groupId>
<artifactId>HikariCP</artifactId>
<version>2.7.4</version>
</dependency>
