[drlvm][winx64] drlvm crashes with large pages enabled 
-------------------------------------------------------

                 Key: HARMONY-3558
                 URL: https://issues.apache.org/jira/browse/HARMONY-3558
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
         Environment: Windows 2003 server 64bit, DRLVM 64bit - build 20070330.

            Reporter: Rustem Rafikov


DRLVM crashes both with gcv4.1 and gcv5 if using large pages with large enough heap size.
Details:

1. GC4.1:
VM crashes if heap size requested > ~900M and works otherwise. It crashes with:
win64-20070330/bin/java.exe -Xms1024m -Xmx1024m -Xem:server -XX:gc.lp=true -Xverbose:gc.lp
-c
p ./jbb.jar;./check.jar spec.jbb.JBBmain -propfile SPECjbb.props

gc.lp: large pages are allocated

java/lang/ExceptionInInitializerError : (null)
HMYEXEL062E Internal VM error: Failed to create Java VM
FAILED to invoke JVM.

2. GCv5:
Due to a bug in gcv5 parsing parameters functtion yuo should specify -XX:gc.use_large_page=true
 -XX:gc.large_page=true 
Command line:

win64-20070330/bin/java.exe -Xem:server -XX:vm.dlls=gc_gen.dll -XX:gc.use_large_page=true
-XX:gc.large_page=true -X
s1500m -Xmx1500m -cp ./jbb.jar;./check.jar spec.jbb.JBBmain -propfile SPECjbb.props.short

it crashes with the message:

java/lang/ExceptionInInitializerError : (null)
HMYEXEL062E Internal VM error: Failed to create Java VM
FAILED to invoke JVM.
GC use large pages.

So,  in the both cases there is the messages that large pages are allocated.
