> TLAB allocation in MacroAssembler::store_inline_type_fields_to_buf looks duplicated with MacroAssembler::tlab_allocate, we might use existing MacroAssembler::tlab_allocate instead of duplicated ones. It will generate safer and faster code. (See details on JBS). All jtreg tests are passed with slowdebug mode. When UseTLAB is disabled, we can also try to allocate the buffer object in eden space.
