JDK-8143843 :  
Applet startup time under IE increased significantly with 8u60. It is 
approximately 10-20 times slower with 8u60 compared to 8u51.

With the attached testcase we see the following results:

IE 11 - Java 8u60
- First time:  around 28 seconds
- 2nd time:  around 20 to 25 seconds
- After browser restart: 25 to 28 seconds

IE 11 - Java 8u51
- First time:  around 5-8 seconds
- 2nd time:  1 second
- After browser restart: around 5-8 seconds

The problem is not reproducible with Firefox.

There are a few existing bugs which appear to report similar behavior.
JDK-8134741 seems to describe a similar issue. 8134741 was closed as
a duplicate of 8134469.  8134469 appears to be specific to situations in
which multiple applets are loaded concurrently, unlike the situation
presented here.  8134469 was closed as a duplicate of 8133665.  A fix for
8133665 was integrated into 8u65-b14, but we tested that build also exhibits
the same startup time regression.

Returning the value of "Resolved In Build" field of this bug to the originally set "b05" value.
