Pascal Schumacher updated GROOVY-7351:
--------------------------------------
    Description: 
When using BSF to interact with GroovyEngine it was seen that a Groovy class that was created as a result of a previous execution was not available for subsequent execution when GroovyEngine was used.
If CachingGroovyEngine was used, it would work.
Sample code is given below

{code}
public class GroovyUsePreviousClass {

	public static void main(String[] args) {
		try {
			String myScript1 = "public class BSFHelloWorld {\n public static void main(" +
					"String[] args ) { println(\'BSF: main: Hello World!\'); }\n };";
			String myScript2 = "import BSFHelloWorld;\n inst = new BSFHelloWorld();\n";
			BSFManager bsfm = new BSFManager();
			// Problem can be resolved by uncommenting the line below:
			//BSFManager.registerScriptingEngine("groovy", "org.codehaus.groovy.bsf.CachingGroovyEngine", new String[]{"groovy", "gy"});
			BSFEngine anEngine = bsfm.loadScriptingEngine("groovy");
			anEngine.exec("Step HelloWorld1", 0, 0, myScript1) ;
			anEngine.exec("Step HelloWorld2", 0, 0, myScript2) ;

		} catch (BSFException bse) {
			bse.printStackTrace();
		}
	}
}{code}
