This happened to me after upgrading to ubuntu 14.04 using Oracle Java 7. In the Aptana folder there is hs_err_pid ... log. Opening the last of them, I saw:
# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again
So, I opened the terminal, and I worte directly:
ulimit -c unlimited
and it worked for me. No problem so far.
