Workarounds

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.
