wrong/strange exceptions

Sun Feb 18 16:11:00 GMT 2007

Hey all
Here an example of wrong/strange stacktraces. I would expect something like:
----- start -----
Exception in thread "main" java.lang.NullPointerException: TestException
	at JniTest.findClass(Native Method)
	at JniTest.main(JniTest.java:8)
1. But on Linux, I get:
----- start -----
Exception in thread "main" java.lang.NullPointerException: TestException
 at java.lang.reflect.Constructor.newInstance(natConstructor.cc:92)
2. On mingw, without Ranjits patch that breaks jni libs [1], I get:
----- start -----
Exception in thread "main" java.lang.NullPointerException: TestException
 at java.lang.VMThrowable.fillInStackTrace(JniTest.exe)
 at java.lang.Throwable.<init>(JniTest.exe)
 at java.lang.Exception.<init>(JniTest.exe)
 at java.lang.RuntimeException.<init>(JniTest.exe)
 at java.lang.reflect.Constructor.newInstance(JniTest.exe)
 at JniTest.findClass(JniTest.exe)
3. On mingw, with Ranjits patch, I get:
----- start -----
Exception in thread "main" java.lang.NullPointerException: TestException
 at 
java.lang.reflect.Constructor.newInstance(/usr/local/src/gcc/libjava/classpath/java/util/regex/PatternSyntaxException.java:130)
 at 
JniTest.findClass(/mnt/daten/tmp/trace-tests/jni-test/JniTest.java:10)
 at JniTest.main(/mnt/daten/tmp/trace-tests/jni-test/JniTest.java:9)
Comments to these three results? Especially case 3 seems to have done 
something horribly wrong when pointing to 
/usr/local/src/gcc/libjava/classpath/java/util/regex/PatternSyntaxException.java:130.
