Research direction

Start in src/com/sun/jna/NativeLibrary.java at lines 186-188 and inspect how searchPaths, the ConcurrentHashMap, and the synchronized block are used there. Determine whether the synchronization is needed and whether the update target is correct; the work is done when the synchronization behavior is justified and the relevant existing behavior remains intact.

Written by the indexing model from the issue text.

Description

The synch. here appears to be unnecessary:
https://github.com/java-native-access/jna/blob/365629530635440381f63939f7891456992fe91b/src/com/sun/jna/NativeLibrary.java#L186-L188

searchPaths is a ConcurrentHashMap, so does it need synch?
It also does not make sense to me to synch. on the value being added, rather than the target being updated.
