[OpenJDK 2D-Dev] RFR: 8263893: getPrinterNames() leaks nameArray if Java String allocation fails

[Alexey Ivanov]

If `JNU_NewStringPlatform` fails to allocate new Java String object for printer name, `std::bad_alloc` is thrown. The handler for the exception does not release the local reference to the `nameArray`, thus it will be leaked.
