Is this a bug?
What causes the build to be interupted?
How do I solve this issue?
or my RAM is too low?

diptaisme,

Sorry to hear you are running into this issue. Thank you for sharing your installation details and error log file.
Have you had this problem before? Were you able to use MyEclipse Java Enterprise perspective before? Did anything unusual happen during the last ME session.
I would recommend you open a new workspace and give it a shot. Open MyEclipse IDE, from menu options click on File > Switch Workspace > Other.
If this does not work, I would recommend you repair/ reinstall your ME profile. Double click on your installer file, this would show you 4 different options, you could choose to repair / re-install ME profile. Please follow the wizard till completion.
Please note that the RAM settings mentioned is fine but the memory settings are a little different from the recommended (MaxPermSize would normally be recommended at 384m for an Xmx setting of 768m), though that wouldn't be an issue.

In case the issue persists, please attach the complete .log file.

Let me know how this works for you?

diptaisme,

If the new workspace doesn't fix the problem, it might be an opportune time to download and install MyEclipse 10.5, our latest release, rather than reinstall 8.6.1. Your license allows you to install all releases while your license is valid and you can install alongside 8.6, if you wish.
