#1783 closed defect (fixed)

Can not upgrade to 0.9.25 on OSX

Reported by: lunokhod Owned by:
Priority: major Milestone: 0.9.26
Component: installer Version: 0.9.25

I have been using I2P on OSX for a long time and have never had any problems upgrading when a new version comes out. Now, however, in the i2p console, I am getting the following message:

Update available: Version 0.9.25
Requires Java version 1.7 but installed Java version is 1.6.0_65

I don't understand this, because I have Java version 1.8 installed!

First of all, at the terminal, "which java" gives me this location for the binary, which is the system default: /usr/bin/java

Second, java -version gives: java version "1.8.0_71"

Third, the system preferences java control panel says that I am using "Java 8 update 77"

I have no idea where "Java 6" might be installed on my machine. I have also looked to see if there was any "JAVA_HOME" variable defined in my login shell, but I didn't see anything.

Any help would be greatly appreciate!

Seems to be a common problem with Mac users.

I found the following in the 'i2prouter' script, perhaps it's a clue:

# OSX always places Java in the same location so we can reliably set JAVA_HOME
if [ "$DIST_OS" = "macosx" ]
    if [ -z "$JAVA_HOME" ]; then
        JAVA_HOME="/Library/Java/Home"; export JAVA_HOME

Alias to current java version is /Library/Java/Home? but "This link only exists for legacy purposes, and will not be updated by installing Java 7. Do not use this path."

"The location has changed from Java 6 (provided by Apple) to Java 7 and onwards (provided by Oracle). The best generic way to find this out is to run


This is the natively supported way to find out both the path to the default Java installation as well as all alternative ones present."

In 53b8f66487fee0aa4e9c59a4a60c39b199e017fe to be 0.9.25-11, new installs only.

Simple fix for existing installs (OS X 10.5 or later): in i2prouter, change the line

        JAVA_HOME="/Library/Java/Home"; export JAVA_HOME


        JAVA_HOME=`/usr/libexec/java_home`; export JAVA_HOME
