Freemind, keyboard becomes unresponsive in 14.04 at random

What is the output of:

java -version; lsb_release -a; uname -a

Thanks

Have you tried Oracle Java? Webupd8 has a PPA which makes installation of Oracle Java super easy. You are currently using Open Java.

Never knew about Oracle Java, only about sun java. Anyway will install jre 1.7 from sun's site if that is the only workaround and like earlier versions of freemind should solve the problem.

Oracle bought Java from Sun.

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

3 commands to install Java. It will also auto update as the PPA is updated. Use TAB and ENTER to accept the licence

Thankyou Andrew. After installing as instructed by you and checking freemind for some time--will revert back here.

On giving the following command in the terminal
freemind
I get the following message
[warning] /usr/bin/freemind: No java runtime was found
[error] /usr/bin/freemind: Unable to find an appropriate java runtime. See java_wrappers(7) for help

even though oracle java has been installed as instructed (and openjdk removed via synaptic).

/usr/bin/java exists and runs but /usr/share/freemind/freemind.sh cannot be deciphered for source of error.

Have you checked in /usr/share/freemind/freemind.sh to make sure it is using the right java binary when it runs?

No, I don't know how to decipher the shell file clearly.

Maybe thought to make a pastebin of the file, so that we can have a look.....

Think about it

This seems to be affecting me too. This same version of Freemind 0.9 was working fine for me in Linux Mint, but now that I did a fresh install of Ubuntu 14.04, Freemind is virtually unusable. The program in general does not become totally unresponsive, just the keyboard.

Here is freemind.sh: http://pastebin.com/BDU2AaE1

Also, when I run Freemind from the terminal, the only output is "Checking Java Version...". No errors, even when it stops responding.

I think it is working fine for me now that I have successfully installed oracle-java8-installer. Thanks!

The same problem has returned. Here is my Java version info.

java version "1.8.0_11"

Java HotSpot(TM) Server VM (build 25.11-b03, mixed mode)

I pasted the usr/share/freemind/freemind.sh at http://pastebin.com/UWAURREG

Had tried to completely remove and reinstall freemind using synaptic but
that did not work--it still gives the same error

Made a copy of the shell file and inserted JAVA_CMD="/usr/bin/java" at the
start of the findjava function definition but that also did not work.

Am making do with the latest version of freemind viz 1.0.1 downloaded from the net. As version 0.9 bundled in ubuntu 14.04 is buggy.

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

JAVA_HOME and PATH environment variables have to be set.
Thereafter freemind (and freeplane) works.

How to set environment variables systemwide can be seen here:
https://help.ubuntu.com/community/EnvironmentVariables#System-wide_environment_variables
OR
You might want to set the environment variables locally for your user profile only. Then you have to edit ~/.bashrc

Example:
export JAVA_HOME=/usr/lib/jvm/java-8-oracle
export PATH=$JAVA_HOME/bin:$PATH

I guess the bug can be closed.

Ignore the last line about "I guess the bug can be closed." since the original bug report was about keyboard unresponsiveness.

Thankyou. Will try. As a solution could not be found for a long time, I
stopped using freemind as i forgot how to start it easily after Oracle Java
was installed--was not knowledgeable about shell programming/ shell Path
variables etc and could not troubleshoot my way out of the problem faced
and got mixed up about the various options tried in the past-- removing the
java which was installed by Ubuntu/synaptic when freemind was originally
installed etc.
