mauve tests failing and dumping core with server VM on 64 bit testing - build 65

Tests:
mauve/tests/lang.Double.DoubleTest
mauve/tests/lang.Double.new_Double
mauve/tests/lang.Float.FloatTest
mauve/tests/lang.Float.new_Float
mauve/tests/text.MessageFormat.format

TestBase: /net/sqesvr.eng/export/vsn/VM/testbase/testbase_vm
Mode : -Xcomp
Platform: solsparc
64 bit testing

Note : The above tests passes with int and mixed mode with -d64 and passes with -Xmixed, -Xint and -Xcomp mode on normal client and server mode
Steps to reproduce:

1. cd /net/sqesvr.eng/export/vsn/GammaBase/Bugs/{Bugid}
2. ksh doit

(or)

set JAVA_HOME to /net/sqesvr.eng/export/vsn/VM/merlin/weekly/jdk/latest/{OS}

${JAVA_HOME}/bin/java -d64 -server -Xcomp -classpath ".:/net/sqesvr.eng/export/vsn/VM/testbase/testbase_vm/src/mauve" gnu.testlet.SimpleTestHarness -debug gnu.testlet.java.lang.Double.DoubleTest
