B4J Question Problem with new install

Update Making things worde.

OK I realised I wasnt using the latest version so updated to 7.51. Now it doesnt compile!!!
Is the correct way to update to do a full install over top?

Log ( Source not changed)
B4J Version: 7.51
Java Version: 11
Parsing code. Error
Specified argument was out of the range of valid values.

Hi,
THanks to Microsoft I have had to change my computer to W10. I reinstalled B4J but am having issues with some software that worked on my old machine.
Its basically the Chat program, slightly modified to not use prefix mode (using a PSOC not Arduino so B4R not option)
I changed just this line ( I think)
astream.Initialize(sp.GetInputStream, sp.GetOutputStream, "astream")
It compiles OK. Sees list of COMPORTS , but as soon as I try to connect it crashes with the following
#
# A fatal error has been detected by the Java Runtime Environment:
#
# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x000000007110b5db, pid=18508, tid=16992

# Problematic frame:

Attached is the error log.

Is this anything to do with Java version, or have I forgotten something .

Thanks

@stevewidget have you tried

1. Deleting the .meta file
2. Cleaning the project

Thanks Pete,
Tried that, no differrence, but certainly will intrdouce as standard procedure in future.
My main concern is , is there any changes due to java11 that might affect jserial? or is it my new setup, or my forgetting something obvious.

Check this: https://www.b4x.com/android/forum/threads/updated-jssc-jar.99668/

Thanks Erel,
that fixed it!! I assume that master libraries are automatically reloaded on update, but is there any way/documentation on user libraries that need updating, other than trawling the forum.
Once again thaks.

Perhaps I spoke a little too quickly. Although it does accept data from my device, I note the following in the log
