Hi, I'm currently evaluating JRebel 2.1a for my company. We make extensive use of groovy here, and I've yet to get jrebel working correctly with it. It seems even adding a line of code and recompiling causes anything involving groovy closures to get messed up. I've created a simple groovy example that duplicates this problem:
public class GroovyTest {
public test(){
System.out.println("time:"+System.currentTimeMillis())
// Run, uncomment the line below, and recompile to generate the error
//["a","b","c"].each { String s -> }
[0,1,2].each { int i -> }
["a","b","c"].each { String s -> }
}
public static void main(String... args){
while(true){
Thread.sleep(2000)
new GroovyTest().test()
}
}
}When I run this, then uncomment the commented line of code and recompile, I get the following output:
=============================== [JRebel Spring Framework Plugin DISABLED] ==============================
You can enable Spring Framework Plugin by setting -Drebel.spring_plugin=true.
------------------------------------------------------------------------------------------
Description: Supports adding new beans and adding new bean dependencies using
annotations or XML. Singletons will be reconfigured after the change. It also
supports adding or changing Spring MVC controllers or handlers.
