command: main -XX:+UseG1GC C1ObjectSpillInLogicOp G1 barriers use logical operators (xor) on T_OBJECT mixed with T_LONG or T_INT. The current implementation of logical operations on x86 in C1 doesn't allow for long operands to be on stack. There is a special code in the register allocator that forces long arguments in registers on x86. However T_OBJECT can be spilled just fine, and in that case the xor emission will fail.
