Solution Unverified - Updated 2 Aug 2024

Environment

Apache Axis

Issue

We experience high CPU in calls like the following:

"Thread-5612" daemon prio=10 tid=0x0000000066209000 nid=0x42d runnable [0x00002b379b56a000]
   java.lang.Thread.State: RUNNABLE
	at java.util.HashMap.get(HashMap.java:303)
	at org.apache.axis.utils.JavaUtils.isEnumClass(JavaUtils.java:1040)
	at org.apache.axis.encoding.ser.BeanSerializerFactory.init(BeanSerializerFactory.java:49)
	at org.apache.axis.encoding.ser.BeanSerializerFactory.<init>(BeanSerializerFactory.java:42)
	at org.apache.axis.encoding.ser.BaseSerializerFactory.createFactory(BaseSerializerFactory.java:235)
	at org.apache.axis.client.Call.registerTypeMapping(Call.java:2296)

Resolution

Upgrade to latest Apache Axis 1.4 releases or later

Root Cause

Content from issues.apache.org is not included.AXIS-2284
Apache Axis is using a HashMap in an unsafe manner and concurrent access to that map is causing high CPU loops per High CPU due to multiple Java threads accessing HashMap simultaneously
