Where has PrintGCApplicationStoppedTime gone?

[Wojciech Kudla]

Hi,

While evaluating different post-java 8 JVMs I noticed that PrintGCApplicationStoppedTime is an unsupported option now.

According to Chris Newland's awesome list of JVM options it has been removed in Java 9 never to return.

Was trying to find an equivalent option with no luck.
How do we get safepoint metrics on the newer JVMs?

Thanks

W.

Hi

Try -Xlog:safepoint
