I have a problem.

[Questioner]

I have used Forge before, and I really enjoy it. However, due to updating my laptops's OS (to Lubuntu 12.04), it has not been working for a while, and I don't know what to do.

Now, I cant remember which version forge was at before I updated, but I was able to run it by executing the .JAR file, which no-longer works. I get I am supposed to run the .SH file, but Forge does not run, and I get this, in terminal and in forge.log


java.lang.NoSuchMethodError: method java.util.regex.Pattern.quote with signature (Ljava.lang.String;)Ljava.lang.String; was not found.

Has anyone got any ideas on what I can do to get past this?

Can you post the output of:

which java

and

java -version

[Questioner]

Which java gives /usr/bin/java

java -version gives

java version "1.5.0"
gij (GNU libgcj) version 4.5.4

Well, it looks like the JRE being used is Version 5 instead of Version 6. I don't think Forge has supported Version 5 in a few years.

[Questioner]

Ah. That would explain it.

Can anyone tell me how to update to version 6?

EDIT: Nope, can't find the package in the software centre. Also, I thought the JDK included JRE.
EDIT2: Well, trying from the java website doesn't work at all.

[friarsol]

Try: sudo apt-get install sun-java6-jre

[Questioner]

IT WORKS!

What I ended up needing to do was to use the sudo update-alternatives --config java
command to change the version of java that was being used. Forge now works.

Thanks for the help!
