Other references to the jvmti version in the debug agent use the result of calling GetVersionNumber(), which provides a jint. These references are otherwise doing the same bit masking and not seeing this warning. Using the compile time JVMTI_VERSION is appropriate for the code in question (it wants the compile time version), and simply casting it to a jint should resolve the warning.
