MethodHandleNatives dependency on java.sql.DriverManager

An undesirable static dependency from java.lang.invoke.MethodHandleNatives to java.sql.DriverManager leads to the base module to depend on jdbc module.

The implementation of the isCallerSensitive method will ultimately be replaced by checking a specific annotation rather than hardcoded list. This issue is filed to track this static dependency and may close it as a dup of the other issue if the new implementation of this method will be integrated soon into jdk8.
