I have four instances of Lucee running for four sites.
They were all on 5.3.1.95. I upgraded each one to 5.3.1.102 a few minutes ago - except one. One would not upgrade.
I got:
java.lang.NullPointerException
I tried three times.
I restarted the instance of Lucee. Tried again, same error.
I downloaded the core file (.lco) and copied to patches. That updated the version.
Still, want to be able to use the server admin to do this, not sftp.
