Quelea failing to launch

Hi! Long-time Quelea user here. So appreciate this app and this community.

I’ve just downloaded and installed version 2020.0 on a Macbook running OSX Mojave 10.14.6. My Java version is Java 8 update 261.

I have been unable to get either the Mac version or the Cross-platform to launch. Nor am I able to launch any of the previously working Quelea installations.

I receive this error: java quit unexpectedly

My crash report includes:

Any help would be greatly appreciated.

Any help would be greatly appreciated? Or if I’ve I come to the wrong place for this type of question, please point me in the right direction? I am in full-time ministry and use Quelea extensively. Right now none of my versions of Quelea will open. I’m a bit stuck. Thanks!

Hey! Sorry for the delay, all the developers have been rather busy as of late. The issue with diagnosing Mac problems is that none of the Quelea developers have a mac, so this can be a bit tricky. Can you try fully removing Quelea and then installing 2019.1 to get that working again? I’m a bit stumped if 2019.1 worked before and doesn’t work now, as that implies some kind of configuration has changed somewhere.

Also, what version of MacOS are you running?

Hey berry120, thanks for the help. I’m running a Macbook Pro with Mojave 10.14.6.

Good news! A bit before you posted your reply I succeeded in getting Quelea working again. Here’s what I did:

First, I uninstalled Java via the command line:

  • sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
  • sudo rm -fr /Library/PreferencePanes/JavaControlPanel.prefpane

Then I reinstalled an older version of Java Runtime Environment (8u161). All of my Quelea installs worked immediately.

Just to see what would happen, I then upgraded JRE to the latest version. Immediately everything returned to crashing.

I then went through the same procedure of uninstalling JRE from the command line and reinstalling JRE 8u161. Everything returned to working.

Great to hear, and well done!

Sounds like we have a compatibility issue with Macs and the latest version of Java 8, but unfortunately that looks like it’s going to be a bit of a nightmare to track down. I’ll make a mental note of it and if I get my hands on a Mac, I’ll see what I can do about reproducing it (and hopefully fixing it if possible.)

Thanks for your attentiveness to this issue. I appreciate this community and the work of the development team. I have checked out many worship projection applications. Quelea is my go to for many reasons. Now that I can run 2020 I’ve got to give you guys kudos for a fantastic upgrade. The Well done! Song Sequence has been at the top of many wishlists. Planning Center import is HUGELY helpful I also appreciate the expanded Documentation. Keep up the great work and know that your efforts are making a difference.
