Got asked by a member of the vulnerability team if we had a bug on this but I haven't found any.
Running the VM with -XX:CICompilerCount=-1 -XX:-TieredCompilation will lead to creating a GrowablArray with the size -1. When doing raw_allocate for this array we use the size and the element size to calculate how much to allocate and get a native memory allocation failure. Like this:
> java -XX:CICompilerCount=-1 -XX:-TieredCompilation
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 18446744073709551608 bytes for AllocateHeap
# An error report file with more information is saved as:
Running with threads equal to -1 should probably not work but we should make sure we verify the input and provide a better error message.
