Occasionally, our HAPI library blows up with the following exception:
Error while processing message: java.lang.NumberFormatException: For input string: ""
After digging through HAPI source, it was found that the <hapi.home>/id_file has to be removed. Here is an excerpt of the helpful code comment:
/** * Creates unique message IDs. IDs are stored in a file called <hapi.home>/id_file for persistence * across JVM sessions. Note that if one day you run the JVM with a new working directory, * you must move or copy id_file into this directory so that new ID numbers will begin * with the last one used, rather than starting over again. * @author Neal Acharya */
