After a long time waiting, JADClipse is back on the market and fully functional with Eclipse 4.x.
Its home page can be found at: http://marketplace.eclipse.org/node/472922#.UKC1UodJ7D4
For some reason installing it from the Market place failed on my PC (Juno SR1) – but directly setting the update site to be http://feeling.sourceforge.net/update worked fine.
The new version comes with two built-in decompilers: “JD-Core” and “jad“.
One of the hidden upsides is that you no longer need to download “jad.exe” separately – the plug-in comes ready to work.
The only problem I observed so far is that the Output original line numbers as comments and the Align code for debugging options are not doing what they used to do. Perhaps this will be fixed in the future.
