Andrey Adamovich commented on AXIS-2647:
----------------------------------------
We faced the same issue and fixed that by patching Axis code i.e. putting
syncronisation blocks inside TypeDesc class to secure access to fieldElementMap.
> 100% CPU hang in TypeDesc.java:313

> Key: AXIS-2647
> URL: https://issues.apache.org/jira/browse/AXIS-2647
> Project: Axis
> Issue Type: Bug
> Components: Serialization/Deserialization
> Affects Versions: 1.4
> Environment: JDK 1.5.0_10 AMD64
> RHEL4 x64
> Reporter: Patrick Eger
> Priority: Critical
>
> Basically we have a bunch of threads stuck within Axis consuming 100% of our
> CPU. This appears to be during deserialization of a response (from EBay API
> in this instance). My best guess would be some sort of thread-unsafe
> modification to the HashMap used by getFieldNameForElement(), resulting in a
> corrupted internal HashMap state and thusly infinite looping.
