vʌvr (formerly called Javaslang) is a non-commercial, non-profit object-functional library that runs with Java 8+. It aims to reduce the lines of code and increase code quality.
A current limitation of the implementation of virtual threads is that performing a blocking operation while inside a synchronized block or method causes the JDK's virtual thread scheduler to block a precious OS thread, whereas it wouldn't if the blocking operation were done outside of a synchronized block or method. We call that situation "pinning".
IMHO, all synchronizd blocks or methods should be replaced with ReentrantLock usage.
