Lets first take a small(er) step ;
There is an example for java basic : https://github.com/getsentry/examples/tree/master/java/basic
It uses ‘sentry 1.7.5’. Last version of 1.7 branch is 1.7.30 and the latest is 3.0.0. Would it be possible to update this example with version 3.0.0?
It would be nice if the example would also have an example of uncaught exception.
Please take a look at this PR that updates an example to Sentry 3.0: https://github.com/getsentry/examples/pull/59
If it won’t solve your issue - provide please more information about your application. Do you configure Sentry appender in the application or on the application server level? Is it a Java EE application or Spring or something else? If you could provide a minimal example that I could just take and deploy to JBoss it would help me finding an issue.
