Bracketed-Paste resulting in unresponsive shell (macOS + JNA)

[sa-BrigitteHerrmann]

During integration of jline3 into our projects we noticed that copy-and-pasting leads to an unresponsive shell, requiring us to kill the ssh-client process afterwards.

The issue is reproducible on macOS 12.6 on Intel Macs.
After some debugging we found out that only the JNA Pty implementation (JnaNativePty) shows the above problem.
Setting org.jline.terminal.jna=false, i.e. using the JANSI implementation can be used as a workaround in our case.
Neither the simple ExternalTerminal nor the JANSI variant (JansiNativePty) have the described issue.

Currently we suspect that issue only affects the macOS implementation of JnaNativePty, however this still needs to be verified.
