      Description

      Bug coming in from PSR:

      Before Full GC (Allocation Failure), two Young collections were seen without
      reclaiming any garbage in the G1 GC log:

      [Eden: 0.0B(100.0M)->0.0B(100.0M) Survivors: 0.0B->0.0B Heap:
      2038.7M(2048.0M)->2038.7M(2048.0M)]

      Saw this problem in two builds:
      JDK 8 b132 and special build from Bengt:

      1)
      java version "1.8.0"
      Java(TM) SE Runtime Environment (build 1.8.0-b132)
      Java HotSpot(TM) 64-Bit Server VM (build 25.0-b70, mixed mode)
      2)
      java version "1.8.0"
      Java(TM) SE Runtime Environment (build 1.8.0-b132)
      Java HotSpot(TM) 64-Bit Server VM (build
      25.0-b62-internal-201403120746.brutisso.humalloc-prototype, mixed mode)
