The java hotswap feature save a lot of time for me. However, it has many limitations (like schema change is not supported). Any idea if the limitation is going to be addressed any sooner? According to this forum entry, it seems to be ignored.
I know that products like JRebel helps. But does anyone know about any open source tools for this?
