In mainline it is just cleaning up the unused `CheckSanity` method from java_md_common.c file

The issue in JDK 8 is "GCC 14.2.0 reports warning: '%s' directive output may be truncated"
This issue is observed in 8u, but it is applicable in mainline as well. Problematic code in `CheckSanity` function.
