[infinispan-issues] [JBoss JIRA] (ISPN-7079) TransactionAwareKeyCloseableIterator.remove uses previousValue which is never set
William Burns created ISPN-7079:
-----------------------------------
Summary: TransactionAwareKeyCloseableIterator.remove uses previousValue which
is never set
Key: ISPN-7079
URL: https://issues.jboss.org/browse/ISPN-7079
Project: Infinispan
Issue Type: Bug
Affects Versions: 8.1.0.Final
Reporter: Patrick Ruckstuhl
Assignee: William Burns
Fix For: 9.0.0.Beta1, 8.2.5.Final, 8.1.6.Final
TransactionAwareKeyCloseableIterator.remove is implemented as
{code:java}
cache.remove(previousValue);
{code}
But looking at the previousValue it never gets set. This results then in
{code}
java.lang.NullPointerException: Null keys are not supported!

at
org.infinispan.interceptors.TxInterceptor$TransactionAwareKeyCloseableIterator.remove(TxInterceptor.java:568)
{code}
I encountered this when trying to switch infinispan from 7.2 to 8.1 in conjunction with
hibernate-infinispan 4.3 which does the following code to clear the cache:
{code:java}
public static void removeAll(AdvancedCache cache) {
try {
Iterator it = cache.keySet().iterator();
while (it.hasNext()) {
it.next(); // Necessary to get next element
it.remove();
}
} catch (UnsupportedOperationException e) {
// Fallback on using clear for older version
cache.clear();
}
}
{code}
