I was not aware the aggressive options could cause crashing, I've been using them for a while as they seem to reduce garbage collection time but clearly more caution is needed in using them.

I believe I've found a solution, it appears to be an issue with the garbage collector, removing the aggressive optimizations seems to fix the problem, also adding -XX:-UseGCOverheadLimit may fix the problem, a good solution I think on the forge side of things would be to limit the CPU usage ensuring the garbage collector doesn't grind to halt which triggers the GCOverheadLimit or a reduction in memory usage.

Hi, I'm posting on behalf of a user of my pack who is unable to pass the texture baking phase without an out of memory error, I myself have noticed this issue but was able to fix it by increasing -Xmx to 4GB, however for this person even -Xmx 6g does not fix the problem, the only sure fix is to reduce the mod count, no mod in particular seems to be the cause. During the baking process the total memory usage reaches 6.3GB before crashing, there is also 100% CPU utilization, in my case it doesn't exceed 3.8GB which leads me to believe the CPU performance may be a factor in the high memory usage I7 4790 v AMD Phenom II X4 955.
