jdk-sandbox: Changelog

7017009: Secondary out of c-heap memory error reporting out of memory Summary: Use os::malloc() to allocate buffer to read elf symbols and check for null Reviewed-by: zgu, phh, dsamersoff, dholmes, dcubed

6766644: Redefinition of compiled method fails with assertion "Can not load classes with the Compiler thread" Summary: Defer posting events from the compiler thread: use service thread Reviewed-by: coleenp, dholmes, never, dcubed

7012088: jump to 0 address because of lack of memory ordering in SignatureHandlerLibrary::add Summary: Write method signature handler under lock to prevent race with growable array resizing Reviewed-by: dsamersoff, dholmes

7016023: Enable building ARM and PPC from src/closed repository Reviewed-by: dholmes, bdelsart

6588413: Use -fvisibility=hidden for gcc compiles Summary: Add option for gcc 4 and above, define JNIEXPORT and JNIIMPORT to visibility=default, add for jio_snprintf and others since -fvisibility=hidden overrides --version-script definitions. Reviewed-by: kamg, never

7016998: gcutil class LinearLeastSquareFit doesn't initialize some of its fields Summary: Initialize _sum_x_squared, _intercept and _slope in constructor. Reviewed-by: bobv, coleenp

6923430: G1: assert(res != 0,"This should have worked.") 7007446: G1: expand the heap with a single step, not one region at a time Summary: Changed G1CollectedHeap::expand() to expand the committed space by calling VirtualSpace::expand_by() once rather than for every region in the expansion amount. This allows the success or failure of the expansion to be determined before creating any heap regions. Introduced a develop flag G1ExitOnExpansionFailure (false by default) that, when true, will exit the VM if the expansion of the committed space fails. Finally G1CollectedHeap::expand() returns a status back to it's caller so that the caller knows whether to attempt the allocation. Reviewed-by: brutisso, tonyp

6789220: CMS: intermittent timeout running nsk/regression/b4796926 Summary: The reference handler java thread and the GC could dead lock Reviewed-by: never, johnc, jcoomes

6999988: CMS: Increased fragmentation leading to promotion failure after CR#6631166 got implemented Summary: Fix calculation of _desired, in free list statistics, which was missing an intended set of parentheses. Reviewed-by: poonam, jmasa

7014679: G1: deadlock during concurrent cleanup Summary: There's a potential deadlock between the concurrent cleanup thread and the GC workers that are trying to allocate and waiting for more free regions to be made available. Reviewed-by: iveresov, jcoomes

6608385: G1: need to support parallel reference processing Summary: Implement support for ParallelRefProcEnabled in the reference processing that takes place at the end of G1 concurrent marking. Reviewed-by: tonyp, ysr

7014261: G1: RSet-related failures Summary: A race between the concurrent cleanup thread and the VM thread while it is processing the "expanded sparse table list" causes both threads to try to free the same sparse table entry and either causes one of the threads to fail or leaves the entry in an inconsistent state. The solution is purge all entries on the expanded list that correspond go regions that are being cleaned up. Reviewed-by: brutisso, johnc

7013718: G1: small fixes for two assert/guarantee failures Summary: Two small fixes to deal with a guarantee failure (the marking thread should join the SuspendibleThreadSet before calling a method that does pause prediction work so that said method is never called during a pause) and an assert failure (an assert is too strong). Reviewed-by: iveresov, johnc
