How to view "Help Contents" with JDK 8 above update 77

[msminek]

Hi,
I get "HTTP ERROR:500" when I view "Help Contents" in TOS v6.3. How can I resolve this problem ?

HTTP ERROR: 500
Problem accessing /help/index.jsp. Reason:
Server Error
Powered by Jetty://

workspace/.metadata/.log shows

!ENTRY org.talend.platform.logging 2 0 2016-11-10 18:54:42.699
!MESSAGE 2016-11-10 18:54:42,699 WARN  org.eclipse.jetty.servlet.ServletHandler  - 
!STACK 0
org.apache.jasper.JasperException: PWC6033: Error in Javac compilation for JSP
PWC6199: Generated servlet error:
The type java.io.ObjectInputStream cannot be resolved. It is indirectly referenced from required .class files

It seems due to Eclipse defect 390889 as same as ASF Bugzilla – Bug 56543.
I roughly checked the envs below:
- 8U77 & TS 6.1.1/TOS 6.3.0 is OK
- 8U91 & TS 6.1.1/TOS 6.3 .0 is ERROR
- 8U111 & TOS 6.3 .0 is ERROR

I think downgrading JDK is not a good idea.
Does anyone know another workaround?
Regards.

Hi,
Could you please drag a component to job and choose it,click F1 to see if help document can display? Is there any error message in error log(show view-->general-->error log)?

Great! This procedure works fine and no error.  
So, the error I reported occurs to click Help --> Help Contents only.
Thanks.
