> Thread.countStackFrames is/was an ill-defined method that dates from JDK 1.0 > for counting the stack frames of a suspended Thread. The method was > deprecated in JDK 1.2 (1998), deprecated for removal in Java 9, and > re-specified/degraded to throw UOE unconditionally in Java 14. Java 22 would > be a fine time to finally remove this method. > > Code that wants to count stack frames should be directed to use > j.l.StackWalker, or if a tool, then it can use JVM TI and other tool APIs. > > A corpus analysis of 30M classes in 131k artifacts from Maven Central found > only 1 usages to this method. The 1 usage appears to be a class that just > wraps all methods, it doesn't actually make use of it.
