Resolution:
Edit the code to ensure that the type is derived from java.lang.Throwable; then recompile.
Example:
In the following example, the type is derived from java.lang.String. You must change the type to java.lang.Throwable.
class-id a. method-id main static. try display "Hello" catch e as type java.lang.String display "In catch block" end-try end method. end class.
