Аналогичная этой: Проблема

Стоит Java 64bit, увы в системе сменить не могу, т.к. для некоторых приложений нужна именно она. В папке стоит 32-битная.

С 64 битной ваш модуль защиты говорит что работать не хочет:

OpenJDK 64-Bit Server VM warning: You have loaded library /home/user/.minecraftonly/libprotect.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.
