Summary: bad behaviour findByPK with null arg + commit A
Initial Comment:
when using a findByPrimaryKey(null) with commit option
A (meanning cache), the query goes to the instance
cache and it does not like it, throwing a
IllegalStateException instead of having another
behaviour (like ONFE or NPE)
the snippet CMPPersistenceManager#findEntity
if (finderMethod.getName().equals("findByPrimaryKey")
&& commitOption !=
ConfigurationMetaData.B_COMMIT_OPTION
&& commitOption !=
ConfigurationMetaData.C_COMMIT_OPTION)
{
Object key = ctx.getCacheKey();
if (key == null)
{
key = ((EntityCache)con.getInstanceCache
()).createCacheKey(args[0]);
}
// the IllegalStateException is thrown when calling
the line after
if (con.getInstanceCache().isActive(key))
{
return key;
}
}
in addition here is a stacktrace excerpt :
