---------------------------------
Resolution: Fixed
> report-maven-plugin fails to validate simple expression
> -------------------------------------------------------
>
> Key: CAMEL-15811
> URL: https://issues.apache.org/jira/browse/CAMEL-15811
> Project: Camel
> Issue Type: Bug
> Components: tooling
> Affects Versions: 3.6.0
> Reporter: Marco Collovati
> Priority: Minor
> Fix For: 3.7.0
>
>
> Starting from camel 3.6, *camel-report-maven-plugin validate goal* fails to
> validate simple expressions; on console log I see an error *[null]* for every
> expression, also simple ones like *${body.id}*.
> Debugging a bit I found that error is due to a NPE on the *ExpressionAdapter*
> created
> in *SimpleExpressionBuilder.bodyOgnlExpression*, and more specifically in
> the
> *init* method, that uses *CamelContext* to resolve bean language.
> When running from maven goal execution, at a certain point, init method is
> called with a null CamelContext reference and this causes the NPE.
> Below an extract of the stacktrace
>
> {noformat}
> java.lang.NullPointerException
> at
> org.apache.camel.language.simple.SimpleExpressionBuilder$28.init(SimpleExpressionBuilder.java:761)

> In 3.5 **init** method was nor overridden by the *ExpressionAdapter* nor
> invoked in *SimpleFunctionExpression.createExpression*.
