Prokka error message

Good morning.
I was trying to run Prokka on a FASTA file (which worked fine before with other applications in Galaxy), but I received this error message:
" An error occurred with this dataset:

format genbank database [?]

Picked up _JAVA_OPTIONS: -XX:MaxPermSize=2G -Xmx15G -Xms1G
OpenJDK 64-Bit Server VM warning: Ignoring option MaxPermSize; support was removed in 8.0

--------------------- WARNING ---------------------
MSG: No white "

Now, the file is in FASTA format: why does the error message speak of Genbank database? Does the “MaxPermSize” mean sequence titles are too long, by any chance?
Thank you. Regards.

Hi again.
I found somewhere a seemingly unrelated post talking about contig titles being too long. I trimmed down the titles and it started working. Apparently it was just that.
Thanks anyway. Best regards.
