Research direction

Start with src/com/sun/jna/internal/Cleaner.java at lines 61-62 and 79-80. Compare the method-level synchronization with the synchronized blocks covering each method body, then run the relevant JNA tests to confirm behavior is unchanged. Done means the redundant synchronization is removed without changing cleaner behavior.

Description

https://github.com/java-native-access/jna/blob/365629530635440381f63939f7891456992fe91b/src/com/sun/jna/internal/Cleaner.java#L61-L62

The entire body of both methods is part of the synch. block, so it seems unnecessary to synch the method as well.
