JDK-7107135 - Stack guard pages are no more protected after loading a shared library with executable stack
Description
test/runtime/7107135/Test7107135.sh:
       87 echo Test changing of stack protection:
       88 echo ${TESTJAVA}${FS}bin${FS}java -cp ${THIS_DIR} Test test-rw
       89 ${TESTJAVA}${FS}bin${FS}java -cp ${THIS_DIR} Test test-rwx
       90 
       91 if [ "$?" == "0" ]
       92 then
       93   echo
       94   echo ${TESTJAVA}${FS}bin${FS}java -cp ${THIS_DIR} TestMT test-rwx
       95   ${TESTJAVA}${FS}bin${FS}java -cp ${THIS_DIR} TestMT test-rwx
       96 fi
       97 
       98 exit $?

Even if java execution fails, exit code becomes zero after 'if' statement evaluation.
Comments
This is shell script problem, the correct way should record the returned value in a variable to keep it. JAVA_RETVAL=$? if [ "$JAVA_RETVAL" == "0' ]; then #java TestMT JAVA_RETVAL=$? fi exit $JAVA_RETVAL

Execution of Test.java returns nonzero result, so TestMT.java will not be executed. But value of $? becomes zero after 'if'

TestMT.java should return a value like Test.java.
