'An ON clause associated with a JOIN operator is not valid.' failure with 10.3.2.1 passes with 10.2

There is a reproduction attached to DERBY-39 derby-joinon.tar.gz which causes the error:
This is a regresion in 10.3.1.4. It works fine with 10.2.2.0. It is therefore a different issue than DERBY-39 which was reported against 10.0.20. In 10.3 the stack trace is below:

java.sql.SQLSyntaxErrorException: An ON clause associated with a JOIN operator is not valid.
