A recent software was installed on my Samsung SM-A546U.
I can compile java code using ecj as before.
Additionally, dx --dex output=myclasses.dex
Then either add classes.dex to CLASSPATH or using -cp myclasses.dex Abort(s)

dalvikvm -cp myclasses.dex com.me.HelloWorld
Aborted

added echo statement to dalvikvm

exec /apex/com.android.art/bin/dalvikvm -Xusejit:true -Xnoimage-dex2oat -Djava.io.tmpdir=/data/data/com.termux/files/usr/tmp -cp classes.dex com.me.HelloWorld
Aborted

Interesting that both ecj and dx use same dalvikvm, but difference is that -Xcompiler mode seems to work ??? Help

Please guide me to collect any info requested
