Bug ID: 62749
Summary: NullPointerException call MimeHeaders.clear ,
java.lang.ArrayIndexOutOfBoundsException call
SocketBufferHandler.setWriteBufferConfiguredForWrite
Product: Tomcat 8
Version: 8.5.16
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Util

Target Milestone: ----
Hi, we have a spring cloud app in which tomcat-embed(verison:8.5.16) is used.
Sometimes, there are two exceptions that happen to our app. We can't recur them
in our test enviroment.We guess it has something with the high concurrency.
Details as below:
1.java.lang.NullPointerException in MimeHeaders:
