Hi, I just downloaded DW 4.5.1 and installed it on MacOS 10.12.3. I got a java.lang.NullPointerException trying to launch DW 4.5.1. Below is the stack trace. I am using Oracle Java 1.8.0_51

mbp:/Applications/DataWarrior.app/Contents/MacOS$./DataWarri or
java.lang.NullPointerException

Any idea what's mashing the exception?

Thanks,

that was an unfortunate bug that slipped testing: If one had selected the Aqua Look&Feel with a previous version, then version 4.5.1 refused to launch on the Macintosh. Version 4.5.2 fixes the issue.

Thanks for the quick fix. I confirmed that it works now.

I also want to thank you for open sourcing Datawarrior. We as computational scientists in drug discovery need to advocate for the open source model. Our IP are in our molecules, not software developed to support research.
