Failing minimal webapp

Taking an existing Tomcat/webapp installation and running with JDK 1.8 leads to compile errors with Jasper.

It seems due to Eclipse defect 390889  https://bugs.eclipse.org/bugs/show_bug.cgi?id=390889

Attached is a reduced webapp which works fine when run with JDK 1.6 or 1.7 but fails with 1.8.

Comment 1 Robbie Gibson 2014-05-19 10:26:26 UTC

Replacing ecj-P20140317-1600.jar with ecj-4.4M7.jar from http://www.eclipse.org/downloads/download.php?file=/eclipse/downloads/drops4/S-4.4M7-201405010200/ecj-4.4M7.jar seems to fix the problem.

ECJ 4.4RC1 is available.
Should we wait for the official release? (which will happen end of June with Luna release)

Comment 3 Mark Thomas 2014-05-19 11:08:18 UTC

I'd be concerned about regressions using an ECJ RC in a stable Tomcat version. Upgrading ECJ is as simple as replacing the JAR so users impacted by this bug have a simple fix available.

Comment 4 Remy Maucherat 2014-05-19 21:09:18 UTC

It would be a good plan to upgrade 8 asap, however, even if the JDT build is a bit "new".

Comment 5 Mark Thomas 2014-05-20 12:32:45 UTC

I've updated 8.0.x to 4.4RC1 which will be included in 8.0.9 onwards.
