ClassCastException on New Proof

[brlarson]

Attempting File > New Proof and entering "bl.add2i" in the dialog box causes a cascade of ClassCastException below.

I created ccerror.mm (attached)ccerror.mm.zipto have the fewest number of constructs to cause the error.

Closing and re-launching the Terminal window on MacOS cured the problem.

Sorry for the inconvenience.

This is a known issue of using Java >9, but there should be a version check in there to prevent this from happening. My guess is that your installation lied about the version somehow due to a misconfiguration.

Mario,

I figured something was amiss. I ran this (a.k.a MacMMJ2.command) when re-launching:

change java to 1.8

export JAVA_HOME=/usr/libexec/java_home -v 1.8

launch mmj2

java -Xms512M -Xmx1028M -jar /Applications/metamath-SEP2021/mmj2/mmj2jar/mmj2.jar "RunParms.txt" Y "/Users/brianlarson/git/LaTeX-metamath/mm/" "" ""

Others, of course, would have different folder locations.

I've had occasion where the export JAVA_HOME was ignored. Rebooting MacOS was the only thing top fix it.

Note that the script for running on macs is untested and largely unchanged since I started maintaining this project, as I don't have a mac to test with, so if you find an issue in the script please send a PR.
