Please file a bug at the Java Developer Connection (http://java.sun.com/webapps/bugreport) after checking the Bug Parade for duplicates.

This issue seems to be caused by the following change made in OpenJDK7: changeset: 1483:7e2c650b86bc user: mcimadamore date: Wed May 29 14:49:14 2013 +0100 summary: 7160084: javac fails to compile an apparently valid class/interface combination http://hg.openjdk.java.net/jdk7u/jdk7u/langtools/rev/7e2c650b86bc Is it possible to cooperate on creating a simple reproducer which could be send to upstream?
Created attachment 809349 [details] Simplified reproducer $ wget http://repo1.maven.org/maven2/commons-el/commons-el/1.0/commons-el-1.0.jar $ javac -source 1.3 ELParser.java -cp commons-el-1.0.jar
The problem seems to be enum *identifier* (valid in Java 1.4 and older).
Mikolaj, I'm able to reproduce it even on OpenJDK8 and Oracle JDK8, because this change have been backported from 8 as far as I knwo. TY, I'm working on it.
This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle. Changing version to '22'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora22
This is now fixed in OpenJDK 8 by: https://bugs.openjdk.java.net/browse/JDK-8069181 but Oracle didn't backport it to 7, so the bug remains there. As 7 is no longer in Fedora, turning this into a RHEL bug.
