   > @ndimiduk - Did you face any issue due to the lack of assert ? +1 LGTM
   
   Not as of yet. Test runs appear clear and I haven't yet gotten this deployed into the environment where we're experiencing the crashes.
   
   I just wanted to share the patch with you experts early, in case I'm doing something obviously stupid.

Review comment:
       These `assert` are protecting calls to the method invoked by `unsafeCopy`: `Unsafe.copyMemory`. The documentation on that method makes no mention of bounds checking, and indeed I don't think it can because it accepts `Object,long` as parameters describing the source and destination memory addresses.
   
   From AdoptOpenJDK:
   ```
       /**
        * Sets all bytes in a given block of memory to a copy of another
        * block.
        *
        * <p>This method determines each block's base address by means of two parameters,
        * and so it provides (in effect) a <em>double-register</em> addressing mode,
        * as discussed in {@link #getInt(Object,long)}.  When the object reference is null,
        * the offset supplies an absolute base address.
        *
        * <p>The transfers are in coherent (atomic) units of a size determined
        * by the address and length parameters.  If the effective addresses and

   > @ndimiduk - Did you face any issue due to the lack of assert ? +1 LGTM
   
   Not as of yet. Test runs appear clear and I haven't yet gotten this deployed into the environment where we're experiencing the crashes.
   
   I just wanted to share the patch with you experts early, in case I'm doing something obviously stupid.
