Taher Alkhateeb updated OFBIZ-8337:
-----------------------------------
Attachment: OFBIZ-8337-3.patch
This is another major patch which further refactors the startup sequence:
- Delete the NativeLibClassLoader
- Refactor the ComponentContainer and StartupControlPanel to operate without
the NativeLibClassLoader. This substantially simplifies the code
- Declare a URLClassLoader in ComponentContainer that is instantiated upon
building the classpath for all components. This makes the classloader start
in one shot
- Simplify the Config file and remove fields that are not used. Also
refactor some messy logic for loading the props file and other code
improvements
- Refactor all the .properties files for startup to have a consistent
structure that clearly documents all available properties and the
default value for each property. This change is also related to the
changes applied on Config.java
- Remove the declaration of the StartupLoader implementation class
from all startup .properties files because only one implementation exists
and it should be the default always.
- Refactor the loaders retrieval code (main, rmi, test, load-data) defined
in the startup .properties files
- Refactor some switch statements to comply with java coding standards
- Add the DTDs defined in base through Gradle because we removed the
NativeLibClassLoader and the classpath buildup logic in StartupControlPanel

>
> The startup sequence in OFBiz is highly complex and requires improvements on multiple levels including:
> - The entire classpath buildup logic and org.apache.ofbiz.base.start.Classpath needs to be removed. The original idea of classpath isolation between the components created many more problems than it solved, and right now the classpath construction is the responsibility of the build system.
> - The custom classloader needs to be removed as well together with the classpath mentioned above.
> - The StartupLoader interface should remove the start() method and just have two methods, load and unload.
> - The startup sequence should have only one StartupLoader, not an array of startup loaders. This StartupLoader (implemented as ContainerLoader) is the only class responsible for bootstrapping OFBiz
> - The ContainerLoader needs to be completely refactored, not only to remove the start() method but also to cleanup the very messy logic currently residing there.
