We don't know that this is an issue with glazed-lists, although upgrading to
1.8.0 (from 1.7.0) caused the problem to surface. An InvalidJarIndexException is
thrown at run-time.

We have a test case that does not use any classes from Glazed lists, but does
use Jasperreports which can use ECJ internally to compile Java code. When the
glazedlists-1.8.0.jar file is appended to the classpath, ECJ throws the
exception, causing the program to error. (Tested on XP and Vista using Java
1.6.0u13).

We have managed to reduce the problem to a test case. The problem seems to be
related to glazed lists, but we are not sure how. The classloader throws an
exception when navigating the the package of the test case; it loads the "com"
package correctly, but throws an InvalidJarException when trying to load the
"com.actual_systems" package (an ancestor package of the test case).

The problem occurs when the test case is in a sub-package at least three levels
deep, and when using glazedlists-1.8.0-java15.jar on the classpath. Replacing
glazedlists-1.8.0-java15.jar with 1.7.0-java15.jar, or removing it completely,
causes the error to go away and the program then works as expected. The program
also works as expected when placed in the main package or the "com" package.

The program can also be made to work by changing the text-field expression not
to include a reference back to the class (although this isn't a good workaround
for us).

The program also works if ECJ is removed from the classpath and
Glazedlists-1.8.0. is added (although the program won't then run without a Java
compiler, e.g. when run over web start). We have also tried different versions
of ECJ.

The test case is:

seems to be related to issue
https://glazedlists.dev.java.net/issues/show_bug.cgi?id=463
which was discovered and fixed after the 1.8.0 release.
You could try to regenerate the jar index of the Glazed Lists 1.8 jar file:
jar i <GL-jarfile>

Let us know if this helps.
