The one not showing up in hl is ID 6574352

java.lang.RuntimeException: playSource() encountered unexpected exception java.lang.RuntimeException: playSource() encountered unexpected exception

Caused by: java.lang.NullPointerException

which is, however, preceded by

playSource():

which IS in hl. So, this might not be an issue.

Looking at an example: ID in hl 6598150 is likely associated with callId 13355e43c3247ef8fe54ec9f7cab8bfc@141.31.8.62 whose scope is ID 6597140 to 6598138.

I assume that every null pointer exception that is catched properly in the code and thus not crashing cairo immediately is only showing up when the catch block creates a log message. We might need to manually add these because the stacktrace is not logged.
