 - when it executes a blocking operation inside a native method or a foreign function
 
 It can be reasonably easy to avoid these situations in your code, but verifying every dependency you use is hard.

+Typically, while experimenting with virtual threads, we realized that versions older than 42.6.0 of the link:{pgsql-driver}[postgresql-JDBC driver] result in frequent pinning.
 Most JDBC drivers still pin the carrier thread.
-Even worse, lots of widespread libraries are pinning and would require code changes.
+Even worse, many libraries require code changes.

+IMPORTANT: This information about pinning cases applies to PostgreSQL JDBC driver 42.5.4 and earlier.
+For PostgreSQL JDBC driver 42.6.0 and later, virtually all synchronized methods have been replaced by reentrant locks.

 ==== The pooling case
 Some libraries are using `ThreadLocal` as an object pooling mechanism.
