Doc Text:
_ecj_ rebased to version 4.5.2 The _ecj_ package has been upgraded to upstream version 4.5.2, which provides a number of bug fixes and enhancements over the previous version. Notably, support for features added to the Java language in version 8 has been completed. As a result, compilation of Java code using Java 8 features no longer fails. This includes cases where code not using Java 8 features referenced code using these features, such as system classes provided by the Java Runtime Environment.

Description Elliott Baron 2016-09-27 17:23:17 EDT 
While RHEL 7 contains a newer ECJ release than RHEL 6, it is still older than 4.4. Thus it does not have full compatibility with Java 8. While Tomcat on RHEL 7 does not exhibit the behaviour seen in bug #1223609, it is possible that similar issues will arise in RHEL 7 due to future JDK 8 updates.

+++ This bug was initially created as a clone of Bug #1336481 +++

With the latest update to java-1.8.0-openjdk (java-1.8.0-openjdk-headless-1.8.0.91-0.b14.el6_7.x86_64) all JSP compilation for tomcat6 is broken. The workaround for the problem is to revert the java update to a previously stable release.

The reason for the problem is that ECJ's JDTCompiler classes have some sort of incompatibility with the OpenJDK update's java.io.ObjectInputStream class. This compatibility issue is causing an exception and preventing JSPs from compiling on tomcat6. See attached bug (https://bugzilla.redhat.com/show_bug.cgi?id=1223609#c13) for more details on this.

Is it possible to rebase ECJ to at least 4.4 to correct this?
