Could not initialize class org.eclipse.birt.chart.device.image.PngRendererImpl

Hello,
 I've been successfully running BIRT reports using birt-runtime 4.3.1 on tomcat 7 (jre7) on Linux for about a year now with no problems. Suddenly, this week any report that contains a chart, any chart, displays the following error message:
 
java.lang.NoClassDefFoundError: Could not initialize class org.eclipse.birt.chart.device.image.PngRendererImpl
 
Reports that don't contain charts still work just fine. Nothing on the server has changed so I'm a little perplexed why this just started.
 
My apologies if this has already been addressed on this forum. 
Thanks!

That seems odd. No java updates or anything have happened? Not a chance that anyone changed something?
 
Could you try downloading the runtime again and replace your existing jars to see if that solves it? Though, like you, I don't see why that would just break.

Thanks Michael,
 It's back working now. I did as you suggested and downloaded a runtime again and installed. This time, using 4.4.1 I tried running it and again it didn't work, but at least it gave me a more helpful error message. This time it told me that libgcc_s.so.1 was missing. I then copied this file from another server, restarted tomcat and now all charts are working. Both using the 4.4.1 version and the 4.3.1. I have no idea how this file got removed from the system in the first place, but restoring it seemed to be the fix.

Great to hear! Very odd. Glad it's working.
