null pointer error during generation engine initialization

[Anonymous]

After a reinstall I am getting this error upon start up:
!ENTRY org.eclipse.core.jobs 4 2 2013-02-13 11:42:34.623
!MESSAGE An internal error occurred during: "Generation Engine Initialization in progress...".
!STACK 0
java.lang.NullPointerException
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:70)

What would cause this and how do I go about troubleshooting this error?

Hi,
Which talend product do you used? Is there any error log which is located in <Talend Studio install path>/workspace/.metadata, more info will be preferred.

Some problems here. My scenario is as follows:
1) We were running TIS, version 4.2.3 with our projects stored on a SVN server
2) I did a COMPLETE export of all objects
3) I did a FRESH installation of 5.3.1 (Build id: r104014)
4) The installation finished succesfully but when I entered our "custom components" directory through the preferences, I reveived the same error as the topic starter.

Hi rogierlommers,

I did a FRESH installation of 5.3.1 (Build id: r104014)

Is it enterprise subscription version?
For enterprise subscription version, these custom component can be shared. See the related article Sharing custom components.
For community version, you can just migrate the custom component item into new studio. If you use it in job design, you need reinstall the custom component into new studio.
Hope it will be useful for your work.
Best regards

Hi Vaibhav,
     I also faced the same issue with Talend 5.2.2 and as per your suggestion, I changed to 1.7 Java and it started working fine. Thanks a bunch for the advice 🙂
