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

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