[JBoss JIRA] Commented: (JBREM-552) cannot init cause of ClassCastException
by Jens Mueller (JIRA)
[ https://issues.jboss.org/browse/JBREM-552?page=com.atlassian.jira.plugin.... ]
Jens Mueller commented on JBREM-552:
------------------------------------
A very similar issue happens reproducibly in JBoss 4.2.3.GA when first after deployment inserting an element in a Google Guava Map created with new MapMaker().softValues().maximumSize(cacheSize).makeMap():

> Look at line 447 and you'll see it is trying to init the cause of a ClassNotFoundException. Running in a debugger, the newly constructed exception created on 446 has a null cause. Looking then at Throwable.initCause and you'll see a null cause causes this IllegalStateException to be thrown. The cause needs to be "this", not null (I don't know why, seems like it should also look for null, but whatever - that's the way the JDK is written).
> The fix is simple - use the constructor that takes a throwable as its second parameter. Not sure why initCause it being used, as opposed to this constructor.
> e.g.:
> new ClassNotFoundException("Can not invoke loadClientInvokerClass method on " + transportFactoryClass, e);
> (notice the ", e" parameter).
> There are three other instances where initCause is called on ClassNotFoundException that also need to be fixed. See the other catch clauses in here.
