Francesco,
If your product is to run on a pristine RHEL 6.5, I believe that the version of glibc you need to link against is glibc 2.12.
This means that if you're building a toolchain that is designed to run binaries on RHEL 6.5, you need to make sure your toolchain sysroot doesn't have a glibc version that exceeds the version on RHEL 6.5.
Otherwise; you'll get lots of runtime errors where the loader (dynamic
linker) can't find the proper versioned symbols because the system glibc is older than what was linked against (for instance if your sysroot had GLIBC 2.19).
I don't know about Java compatibility with glibc 2.19.
