#11397 closed defect (fixed)

[PATCH] NullPointerException when item is retrieved from the TMS cache

Reported by: wiktorn Owned by: Don-vip
Priority: major Milestone: 15.05
Component: Core imagery Version:
Keywords: regression Cc:

Description

In [8303] there was introduced transient keyword to HashMap in:
​http://josm.openstreetmap.de/changeset/8308/josm/trunk/src/org/openstreetmap/josm/data/cache/CacheEntryAttributes.java

This makes, that every time when tile is fetched from Cache, HashMap will be empty, so getLongAttr will throw NullPointerException.

This must be non-transient field. Better approach is to change the type from Map to HashMap, so the code will be guaranteed to be serializable.

Don,

Why you decided to leave Map interface instead of HashMap as CacheEntryAttributes.attrs type specification?

comment:5 Changed 9 years ago by Don-vip

Because it would trigger another sonar warning :-) I think I will disable the one about serialization.
