eclipse - The type java.io.ObjectInputStream cannot be resolved. It is indirectly referenced from required .class files

Question

I have downloaded Eclipse and tried to create a sample servlet program but I got following error

The type java.io.ObjectInputStream cannot be resolved. It is indirectly referenced from required .class files

I have configured build path correctly. I am using Java 8 and Apache Tomcat 7 and libraries for both are referenced correctly.

Problem is specifically for Java EE only. Ordinarily Java SE projects are running fine.

Answer 1

Something happened in Java 8 Update 91 that broke existing JSP code. That seems pretty clear. Here is a sample of similar questions and bug reports:

• Unable to compile JSP file with JDK1.8.0_92
• Spring MVC - Unable to compile class for JSP
• Unable to access CloudPlatform Client
• https://bugs.openjdk.java.net/browse/JDK-8155588 (closed as "not an issue")
• https://bugs.openjdk.java.net/browse/JDK-8155223 (closed as "not an issue")
• https://access.redhat.com/solutions/2294701
• https://alluxio.atlassian.net/browse/ALLUXIO-1956
• https://jira.atlassian.com/browse/CWD-4729

• https://issues.apache.org/jira/browse/OOZIE-2533 (from a comment: "This is really looking like a JDK bug")
• https://bugzilla.redhat.com/show_bug.cgi?id=1337940 (comment 2 mentions the change to java.io.ObjectInputStream in Update 91 that "made it incompatible with RHEL6's current ECJ version")
• https://github.com/mit-cml/appinventor-sources/issues/814
• https://community.oracle.com/thread/3953395

All these are about problems with Java 8 Update 91 (or later) that are not present when using earlier JRE/JDK versions.
