…erFactory class for virtual-threads The getBinder method in DefaultBinderFactory was made thread-safe using ReentrantLock. This commit ensures that the method is friendly for virtual threads to avoid blocking and pinning. The lock is acquired at the beginning of the method and released in a finally block to ensure it is always released, even if an exception occurs. Fixes spring-cloudgh-3004
