Dbms.logs.query.allocation_logging_enabled gets java.lang.ArrayIndexOutOfBoundsException: Index 256 out of bounds for length 256

I am trying to profile the memory consumption of queries, since we are experiencing java Heap space crashes.

I enabled the dbms.logs.query.allocation_logging_enabled setting
together with the dbms.track_query_allocation=true param.

But I am getting an exception, seems like a bug.

neo version: 4.0.5

pr, I_s, s RETURN * - {} - {} Index 256 out of bounds for length 256
java.lang.ArrayIndexOutOfBoundsException: Index 256 out of bounds for length 256
