      DSA keySize < 1024, include jdk.disabled.namedCurves, \
      SHA1 denyAfter 2019-01-01
 
Remove the last entry together  with the preceding “, \” character. Finally, the property should look like this:
 
jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024, \
      DSA keySize < 1024, include jdk.disabled.namedCurves
