[Eclipse] DLTK crashed with error message “Open Type Hierarchy action”

Context :

Eclipse 3.7.2 (Indigo)

Problem / Error:

An internal error occurred during: "Open Type Hierarchy action".

Solution (reblog la solution) :

PDT 3.1.1 requires DLTK 4.0, and there is no such version of DLTK in Indigo repository.
When you installed PDT 3.1.1 on Indigo, DLTK 3.0 in Indigo repository is applied because of mal-dependencies in PDT. It doesn’t work.

You can choose several ways to fix the problem.
1) Upgrade to the latest stable Juno 3.8.1.
2) Downgrade to the latest bug-ful Juno 4.2.1 having too much problems.
3) Install DLTK 4.0 into your Indigo installation.
4) Drop PDT.

If you are going to install DLTK 4.0 into your Indigo,
Go to Help>Install New Software
Add “http://download.eclipse.org/releases/juno
Check “Dynamic Languages Toolkit – Core Frameworks” (under General Purpose Tools category)
Go ahead.

Note that this updates “EMF – Eclipse Modeling Framework Core Runtime”(from 2.7 to 2.8 ) also. I don’t know whether this will cause other problems or not against other than PDT.

[Eclipse][Oracle JDK] Eclipse Indigo crashes at startup in Ubuntu 12.04

Problem :

Eclipse crashes at startup in Ubuntu 12.04 displaying an error dialog with the message “An error has occurred. See the log file /home/user/.eclipse/org.eclipse.platform_3.7.0_155965261/configuration/[a_long_number].log.” The log file is attached to the report.

Solution :

Eclipse Indigo is not compatible with Oracle’s JDK, in my case, it is JDK 1.6.0_45.

But it works with Open jdk, so idea is to change Oracle JDK to Open JDK in ubuntu 12.04
