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 C:\Program Files\Java\jre1.8.0_181\lib\security\lib\security\java.security
# jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024
After that, the JNLP file will be running as usual again.
