If the file DhSQLException.java, (see attachment) is javac using JDK 1.1.6 it compiles with out errors. Then when you try to generate a header using javah com.progress.sql.sp.DhSQLException, (still using JDK 1.1.6) the following errors are seen.
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"
com/progress/sql/sp/DhSQLException: no such class
This does not happen with JDK 1.1.5.
