please find the updated webrev(http://cr.openjdk.java.net/~vtewari/8165437/webrev0.7/index.html).
This change is broken on 32-bit systems - JVM_Nanotime returns a jlong which is always 64-bit, but the code uses long for the nanotimeout values, which will be 32-bit on 32-bit systems!
This change appears to be causing massive testing failures due to jtreg agentvm failing due to sock connection issues. Most obvious with 32-bit linux builds. However we also see a some failures on OSX which is not explained by the long vs jlong issue.
