---------------------------------------

             Summary: 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


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

 java.lang.NullPointerException
 at org.apache.camel.language.simple.SimpleExpressionBuilder$28.init(SimpleExpressionBuilder.java:761)
 at org.apache.camel.language.simple.ast.SimpleFunctionExpression.createExpression(SimpleFunctionExpression.java:61)

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