RFR: JDK-8200115: System property java.vm.vendor value includes quotation marks

[Erik Joelsson]

Hello,

Since JDK-8189761, the java.vm.vendor string for an OracleJDK build 
contains quotation marks. This would also be true for any other build of 
OpenJDK where the user set the --with-vendor-name configure option.

I found the culprit of this to be the combination of the build setting 
the preprocessor flag as -DVENDOR='"value"' (double quotes inside single 
quotes) and vm_version.cpp using the XSTR macro to convert the value of 
VENDOR into a C string. The -DVENDOR argument is also given to libjava, 
where System.c does not apply a similar conversion, so it requires the 
double quotes to be supplied on the command line.

I found the simplest solution for unifying the behavior between libjvm 
and libjava to be to remove the XSTR macro call in vm_version.cpp.
