I've done manipulations of binary executables myself (on Windows). For release level software, where debug info such as symbol names is totally no where to be found, all you can use is a disassembler and a hex editor. A slight mistake in changing the bits and bytes in the binary will just crash the software without telling you what the problem is. I actually really admire those who can make sense of obfuscated native binary code without debug info.. but decompiling java code using "off-the-shelf" tools is totally different.. the difference is like playing mozart on piano v.s. ... on your ipod.....
