<i18n dev> RFR: 8255917: runtime/cds/SharedBaseAddress.java failed "assert(reserved_rgn != 0LL) failed: No reserved region" [v5]

[Yumin Qi]

> Hi, Please review
>   Windows mapping for file into memory could not happen to reserved memory. In mapping CDS archive we first reserve enough memory then before mapping, release them. For cds archive and using class space, need split the whole space into two, that is, release the whole reserved space and do reservation to the two split spaces again, which is problematic that there is possibility other thread or system can kick in to take the released space.
>   The fix is the first step of two steps:
>    1) Do not split reserved memory;
>    2) Remove splitting memory.
>    This fix is first step, for Windows and use requested mapping address, reserved for cds archive and ccs on a contiguous space separately, so there is no need to call split. If any reservation failed, release them, go to other way, but do not do the 'real' split either. For Windows (and using class space), the reserved space will be released anyway.
