The following resource is signed with a weak signature algorithm MD5withRSA and is treated as unsigned
Just comment out the setting of
jdk.jar.disabledAlgorithms in the file of
lib\security\java.security (which is located at
C:\Program Files (x86)\Java\jre1.8.0_181\lib\security\lib\security\java.security OR
# jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024
After that, the JNLP file will be running as usual again.
