A DESCRIPTION OF THE PROBLEM :
Sending a newly created HashMap over a Remote EJB call in Glassfish and adding an entry to the HashMap in the EJB Method throws an ArrayIndexOutOfBoundsException. It seems that the Map thinks it was already initialized because the check if (table == EMPTY_TABLE) in the put method seems to be false (even if it should the true) -> Hash Seed value was not initialized (=0) when the exception occured.

This is reproducable on Glassfish but not in a normal Unit Test where we tried to serialize/deseriaize the Hashmap before adding a object via put(...)


REGRESSION. Last worked in version 7u25

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
- create a new HashMap
- do EJB call with HashMap
- in the called Method add entry via put


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Entry is added to the HashMap
ACTUAL -
ArrayIndexOutOfBoundsException

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Caused by: java.lang.ArrayIndexOutOfBoundsException: -1761085646
        at java.util.HashMap.put(HashMap.java:498) ~[na:1.7.0_40]


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Add and remove an entry before sending the HashMap in the EJB call.

SUPPORT :
YES
