Hmn, not sure yet, but looks like the map from the Spring Framework I
am using is treating both keys (Class) and values (ClassInfo) as weak
references, not sure yet if this could easily be changed...
No, at least no indication of that so far, seems only to determine
ClassInfo once per class.
Yes, that is the issue, map entries can be garbage collected even if the
class is still loaded (e.g. Integer)...
e.g.
def scriptText = """
class Script1 extends Script {
static class Inner {
int x = 1;
}
Object run() {
print "."
return new Inner().x + new Parallel().y
return x+y
}
}
class Parallel {
int y = 2;
}
