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: P E
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.
