InMemoryJavaCompiler.compile() returns reference to old class when compiling a new class with the same name #16
Description
If I ask InMemoryJavaCompiler to compile a new class with the same name as an existing class, the compile() method returns a reference to the existing class.
Minimal example across two files, both in the default package, compiled and loaded on the classpath:
Example.java:
public class Example {
}
MinimalExample.java:
import org.mdkt.compiler.InMemoryJavaCompiler;
public class MinimalExample {
public static void main(String args[]) throws Exception {
Class<?> oldClass = Example.class;
InMemoryJavaCompiler compiler = InMemoryJavaCompiler.newInstance();
Class<?> newClass = compiler.compile("Example", "public class Example {\n }\n");
if (oldClass.hashCode() == newClass.hashCode()) {
System.out.println("I have two copies of the old class.");
}
}
}
Expected behaviour: the class returned by compile should be the result of compiling the string passed to it.
I think this is a bug.
Thanks very much for providing this library! I am very keen to use it in Gin :-)
