I constantly get the same error during svn update or compare operations in IntelliJ Idea Community edition:
svn: E175002: Received fatal alert: unexpected_messag
Adding -Dsvnkit.http.sslProtocols=SSLv3
option in IDEA_HOME\bin\idea.exe.vmoptions
file resolved issue for me.
See http://youtrack.jetbrains.com/issue/IDEA-90335
I have had a very similar problem to the original poster. The suggestion by Raman above did not work for me. My problem was most likely caused by running IntelliJ in Java 7 combined with a badly configured Apache server serving the SVN. Java 7 implements SNI which can cause connections to incorrectly configured HTTPS servers to fail (where previously with Java 6 they would work just fine).
The solution I used to get around this problem was to add the following line to $IDEA_HOME/bin/idea64.vmoptions or $IDEA_HOME/bin/idea64.vmoptions as appropriate:
-Djsse.enableSNIExtension=false
This will disable SNI extensions for the JVM running IntelliJ (don't use this setting on production server running application - should be ok for VM running dev IntelliJ)
The answer in this reply was culled from this generic stackoverflow post
Just another note on this as I just ran into it. There is a note about this in the release notes for Java 8 Update 60 (8u60) (here: https://java.com/en/download/faq/release_changes.xml) about where the disabled cipher suites are listed, which is in $JAVA_HOME/jre/lib/security
in the file java.security
.
You can re-enable various disabled ciphers by removing them from the disabled list.
HTH someone.
