8009940: G1: assert(_finger == _heap_end) failed, concurrentMark.cpp:809 Summary: Skip reference processing if the global marking stack overflows during remark. Refactor and rename set_phase(); move code that sets the concurrency level into its own routine. Do not call set_phase() from within parallel reference processing; use the concurrency level routine instead. The marking state should only set reset by CMTask[0] during the concurrent phase of the marking cycle; if an overflow occurs at any stage during the remark, the marking state will be reset after reference processing.

README-pre-components:
---------------------
Current pre-components are langtools, jaxws, jaxp, and corba.

Pre-components can use ant to build but must have a make/Makefile for
building (a GNU make Makefile).
All ant knowledge is being isolated in the workspaces that use it.

Also for various reasons it is nice to have a Makefile wrapper over the
running of ant, but in general having to do
anything with shell commands is much easier to do in a Makefile
than in an ant script.

The make/makefile rules are:

 Variables:
  ALT_BOOTDIR           The jdk home to use to build, if provided
  ALT_LANGTOOLS_DIST    The dist area from a langtools build to use, if provided
  ALT_OUTPUTDIR         Parent dir of build and dist directories, if provided
  VARIANT               If DBG, debug build, if OPT, optimized build
  TARGET_CLASS_VERSION  The classfile version number (currently 7)
  ANT_HOME              Home of ant to use, if provided
  QUIET                 If defined, be quiet
  VERBOSE               If defined, be verbose
  JDK_VERSION           Version being built
  FULL_VERSION          Full version string for this jdk build
  MILESTONE             fcs, beta, internal or empty
  BUILD_NUMBER          Number of the jdk build
  JPRT_ARCHIVE_BUNDLE   Path to zip bundle to create for JPRT

 Targets:
  all                   Build everything, including dist
  build                 Build build area
  clean                 Clean up
  clobber               Same as clean (don't ask)
  sanity                Perform any sanity checks, exit non-zero if errors
  jprt_build_product    JPRT product build, zip results into JPRT_ARCHIVE_BUNDLE
  jprt_build_debug      JPRT debug build, zip results into JPRT_ARCHIVE_BUNDLE
  jprt_build_fastdebug  JPRT fastdebug build, zip results into JPRT_ARCHIVE_BUNDLE

Then of course we expect a dist/lib/classes.jar, dist/lib/src.zip and dist/lib/bin.zip.
