ClassNotFoundException in OSGi environment
------------------------------------------
Key: CAMEL-4171
URL: https://issues.apache.org/jira/browse/CAMEL-4171
Project: Camel
Issue Type: Bug
Components: camel-core, camel-groovy
Affects Versions: 2.7.2
Reporter: Sergey Zhemzhitsky
The problem is in the following method of the GroovyLanguage
@SuppressWarnings("unchecked")
protected Class<Script> parseExpression(String expression) {
return new GroovyClassLoader().parseClass(expression);
}
It uses the default constructor to create GroovyClassLoader, which uses Thread
context classloader, which may not be equal to the classloader of the bundle
where the camel context is defined.
