Java RDP applet through APM stops working after update to 8v131
We have been using the RDP applet on a webtop portal page (APM) for quite some time now. However, since the Java update to 8u131 the applet can no longer be used.
The error message is: "Your security settings have blocked an untrusted application from running. The following resource is signed with a weak signature algorithm MD5withRSA and is treated as unsigned: "
After adding the domein to the exception list of on the java client (as a workaround) it does continue but after opening the RDP client the F5 page throw the following error: "access denied ("java.util.logging.LoggingPermission" "control")"
We clearly did miss something since I cannot find any other sources claiming to have this problem. I did find a source claiming this change would be made in Java 8u131: http://www.infoworld.com/article/3159186/security/oracle-to-java-devs-stop-signing-jar-files-with-md5.html
We are running quite an old version of the BIG-IP software: BIG-IP 11.5.4 Build 2.0.291 Hotfix HF2
Is this solved in a later release (in the 11.5.4 branch)? I did stroll through the release notes but did not find anything mentioning resigning the applets. Any ideas?
