import java.lang.annotation.Target;

An annotation expressing that a method is especially sensitive
to stack overflows. This is a hint the JVM can use to grant access to
extra stack space when executing this code if such feature is supported
by the JVM. The JVM is free to ignore this annotation.
A possible way for the JVM to improve the execution context for methods
with this annotation is to reserve part of the thread's execution stack
for them. Access to this section of the stack would be denied by default
but could be granted if the JVM detects a possible stack overflow and
the thread's call stack includes at least one annotated method. Even if
access to this reserved area has been granted, the JVM might decide to
throw a delayed StackOverflowError when the thread exits the annotated
method.
Since:
