java.lang.Error: Bad magic on log file, what does it mean? #15

I am getting the following exception when I tried to create an instance of a 
RecordManager class

Caused by: java.lang.Error: Bad magic on log file

What exactly does this error mean?
Is it similar to the python bad magic number case which is seen when you change 
python versions for compiled code?

Look like db corruption. Not sure why.
