Hi, is it possible using Javassist to understand if a specified instance has a monitor active? I know this is not a problem of reflection, but given an instance CI of class C, if I need to load a modified version of class C to produce CI2 that substitutes CI I should bother with any possible thread blocked on CI. Any idea on this? Thanks, Luca View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4120315#...
