AspectJ scripting agent
=================
Scripting extension for [AspectJ][1] java agent. Allow java bytecode [instrumentation at jvm startup][2] by using [MVEL][3] expression and execute code from [maven artifact repositories][4]
Any AspectJ [pointcut expression][5] available with aspect types: AROUND, BEFORE, AFTER, AFTER_RETURNING, AFTER_THROWING
For [example][6]:
```json
{
"name": "org.aspect.testing.Aspect6",
"type": "AROUND",
"pointcut": "execution(public static void main(String[]))",
"init": {
"expression": "System.out.println(\"Start jvm\")"
},
"dispose": {
"expression": "System.out.println(\"Stop jvm\")"
}
},
```
Agent configuration:
* `org.aspectj.weaver.loadtime.configuration` = `config:file/http` choose "config:file" or "config:http"
* `org.aspectj.weaver.loadtime.configuration.debug` = `true / false`
* `org.aspectj.weaver.loadtime.configuration.filter` = `default - all aspects from configuration`
or any valid MVEL expression to filter aspects by "aspectByInstance/entry/key" value
* `repo.remote.url` = `default - maven central` or http://... valid path to other repository
* `repo.local.path` = `path` - local directory to store maven artifacts
