Testing in jAlbum 26.2.1 and 26.3b3
If I disable background mode, the album generates successfully.
If I enable background mode, album generation fails with error
se.datadosen.util.ScriptException: java.lang.NullPointerException in init.bsh at line number 9
The statement that fails is
new MgInit(engine);
Logged messages show that MgInit.java was partially processed.
System console does not contain the Java error stack, so I can't identify the statement that failed. The stack shows in other circumstances; it just doesn't appear in this situation.
How can I write the Java error stack to system console?
