Hi.
I use poi to read Excel files in a task in Bonita BPM.
When I run this task more than 3 times, it won't work again and I see this error in the log :
org.bonitasoft.engine.connector.exception.SConnect orException: java.util.concurrent.ExecutionException: java.lang.ExceptionInInitializerError
I think it happens because I try to read multiple time in the same file.
I probably need to free memory by closing something in my program but I don't know what.
Here is my code :
I already close the file, bufferInput and OPCPackage.
Did you have and idea of what can cause this problem ?
Thanks in advance.
