Warning: Could not get charToByteConverterClass!

[pawlowska]

The (up to date as of today) openspim version of Fiji throws the "Warning: Could not get charToByteConverterClass!" in the Java console at seemingly random times. I tried a clean Fiji version from Fiji website and I didn't have this warning there. I hope this is the right place to post it.

It looks as if this warning comes from xalan: https://github.com/zxlooong/jdk14219/blob/b9422ce246ee463a24e55f3e91797b33862c9d4c/org/apache/xalan/serialize/Encodings.java#L162

Do you know of any specifics how to trigger this warning?

(I could also imagine that a recent Java version simply removed the sun.io.CharToByteConverter#getConverter(java.lang.String) method... So either a downgrade of Java or an upgrade of xalan might be required to make this warning go away.)

I'm not exactly sure what triggers the warning, there is only this one line in the console. I'll try to pay more attention. Dylan Windell also mentioned this http://openspim.org/pipermail/openspim/2015-June/000756.html so at least it's not specific to my computer.

one of the situations it pops up is after updating, more or less at the same time with the message "update finished, please restart fiji"

Hmm. If I call the Find Jar For Class helper (via Ctrl+L), my Fiji/OpenSPIM claims that the class org.apache.xalan.serialize.Encodings is not even found. Is that the same for you?

[pawlowska]

Yes, it is, i.e. class not found. So it must be a different one then?

Incidentally, I was doing acquisition right now and the console warning popped up right after it was finished.
