Bug 23361 Java Model Exception when renaming a compilation unit
Reported: 2002-09-10 10:28:42 | Status: resolved fixed

Build 200209031019 I have a special test case which generates a Java Model Exception, a funny thing (for me) it's I can't reproduce it two times with the same compilation unit names, even if I stop and restart Eclipse. 1. Create the two following compilation units : public class TestCompiler_1 { public static void main(String[] args) { TestCompiler_2.foo(); } } ------------ public class TestCompiler_2 { public static void foo() { System.out.println("test"); } } 2. Export TestCompiler_2 in a jar file. 3. Add the created jar file in the classpath. 4. Rename TestCompiler_2 to TestCompiler_2_src, in the "Rename compilation unit" dialog, uncheck "Update references to renamed element". The following stack trace is written in the log file : !SESSION Sep 10, 2002 09:11:55.521 --------------------------------------------- java.version=1.4.1-beta java.vendor=Sun Microsystems Inc.
