Xilai Dai commented on CAMEL-14597:
-----------------------------------
Checked also on released 2.25.0, 3.0.1, and the master branch, the same
IllegalAccessException is thrown.
In case of Spring/Spring-DM, the SpringInjector is used to create the bean
instance, where the private default constructor of the class is supported
properly.
{code}
applicationContext.getBeanFactory().createBean(type, autowireMode,
dependencyCheck);
{code}
In case of Blueprint, the DefaultInjector is used to create the bean instance,
but the ObjectHelper.newInstance() seems not properly support the private
default constructor.
{code}
return type.getDeclaredConstructor().newInstance();
{code}
> camel-blueprint - Using simple language on setProperty() failed with
> IllegalAccessException in case of blueprint
