JavaWrapper

java.lang.Object
- org.apache.bcel.util.JavaWrapper

```
public class JavaWrapper
extends Object
```
Java interpreter replacement, i.e., wrapper that uses its own ClassLoader to modify/generate classes as they're requested. You can take this as a template for your own applications.
Call this wrapper with:
```
java org.apache.bcel.util.JavaWrapper <real.class.name> [arguments]
```
To use your own class loader you can set the "bcel.classloader" system property.
```
java org.apache.bcel.util.JavaWrapper -Dbcel.classloader=foo.MyLoader <real.class.name> [arguments]
```
