switched to java 6 and it stared pretty sure i ran it with java 7 (oracle).. but this is the version i use
java version "1.6.0_35"
Java SE Runtime Environment (build 1.6.0_35-b10-428-11M3811)
Java HotSpot 64-Bit Server VM (build 20.10-b01-428, mixed mode)
hello, yes. done some more research and compared the files on win with the on osx and i'm pretty sure that the native-files downloaded to osx are the source for the problem
they are located here
techniclauncher/technicssp/bin/natives/
i ran the "linux"-version on osx and windows (win7) and they both produce the same md5 mismatch error in log, but on win the application starts after login, not on osx :|
i also verified that the md5 checksum on win _is_ wrong
