I'm classifying this as "runtime" instead of "javah" because it is really
a runtime problem. The only reason we don't see it with the interpreter
is because "java.lang.Thread" is always resolved first.

% /usr/local/java/jdk1.1.7/solaris/bin/javah -d /tmp -classpath classes java.lang.Throwable
Signalled error "java/lang/ClassFormatError" with detail "Bad interface index"
java/lang/Throwable: no such class

% /usr/local/java/jdk1.1.7/solaris/bin/javah -d /tmp -classpath classes java.lang.Class java.lang.Throwable
[no error]

This is broken in 1.1.6 and 1.1.7 but is OK in 1.1.5.

with the following file Throwable.java

package java.lang;

public class Throwable {

 }
we have the following error with jdk1.1.7B,
this same test was OK with jdk1.1.4
but it fails with jdk1.1.8_09
and it's OK with jdk1.2.1

javah -classpath $JDK_HOME/lib/classes.zip:./ java.lang.Throwable
Signalled error "java/lang/ClassFormatError" with detail "Bad interface index"
java/lang/Throwable: no such class

we can't use jdk1.2, and we would like a jdk 1.1.x compliant Y2K

Under JDK version 1.1.3 (and I think 1.1.6) I was sucessfully
able to use the following command sequence. The class files
DramaStatus.java and DramaException.java are below.

> javac -classpath .:/usr/java//lib/classes.zip -d . DramaStatus.java
> javac -classpath .:/usr/java//lib/classes.zip -d . DramaException.java
> javah -classpath .:/usr/java/lib/classes.zip:./au/gov/aao/drama/ -jni DramaException


When I tried this under JDK 1.1.8, the javah command failed. e.g.

> JAVA_HOME=/usr/local/java/jdk1.1.8
> javac -classpath .:/usr/local/java/jdk1.1.8/lib/classes.zip -d . DramaStatus.java
> javac -classpath .:/usr/local/java/jdk1.1.8/lib/classes.zip -d . DramaException.java
> javah -classpath .:/usr/local/java/jdk1.1.8/lib/classes.zip:./au/gov/aao/drama/ -jni DramaException
DramaException: no such class


I tried an alternative version of the javah command, as below, since
I beleive the requirement to specify the full package direction
may have been a bug in the older version. There was no change

> javah -classpath .:/usr/local/java/jdk1.1.8/lib/classes.zip -jni DramaException
DramaException: no such class

Finally, I tried the following version

> javah -classpath .:/usr/local/java/jdk1.1.8/lib/classes.zip -jni au.gov.aao.drama.DramaException
Signalled error "java/lang/ClassFormatError" with detail "Bad interface index"
Signalled error "java/lang/NoClassDefFoundError" with detail "java/lang/Throwable"
Signalled error "java/lang/NoClassDefFoundError" with detail "java/lang/Exception"
au/gov/aao/drama/DramaException: no such class



Version details, java 1.1.3

> java -version
java version "1.1.3"
> java -fullversion
java full version "1.1.3n:1997.07.10"


Version details, java 1.1.8

> java -version
java version "1.1.8"
> java -fullversion
java full version "JDK1.1.8M"


In both cases, CLASSPATH was NOT set. Although I did try
setting it to the same values as I was using with -classpath.
