Fixed all error on Zeppelin.java

try { handleException("Debug 1", new RuntimeException()); } catch (Exception e) {};

now getting errors from ParagraphIT

Here's some experiments about ParagraphIT error,

• It passes on my local machine with firefox 31.0 (the same version with travis uses)
• It passes on my travis account, constantly
• It fails on apache travis account, constantly

And i tried narrow down what cause the error on apache travis account, and in case of ParagraphActionIT.testCreateNewButton, it opens paragraph's setting dropdown menu successfully,

And i believe it locates Inserts New button and click(), but nothing happens and test fails.

Sounds great! Shall we merge this guy then, and handle this nasty click in ParagraphActionIT.testCreateNewButton in separate pr?

@bzz @Leemoonsoo, you said "i believe it locates Inserts New button and click(), but nothing happens and test fails".

This may be related to https://issues.apache.org/jira/browse/ZEPPELIN-1033. It's not just integration test which fails, the actual functions seem to be broken.

@bzz Let me merge this into master and branch-0.6 then
@randerzander Thanks for reporting the problem. yes they might be related!
