Marek Handl created SANDBOX-477:
-----------------------------------
Summary: StackOverflowError because hash code used in debug
messages
Key: SANDBOX-477
URL: https://issues.apache.org/jira/browse/SANDBOX-477
Project: Commons Sandbox
Issue Type: Bug
Components: Javaflow
Reporter: Marek Handl
Priority: Critical
JavaFlow often uses hash codes of objects in debug log messages. When the
object is a map that contains a reference to itself, an infinite loop occurs
which ends with a *StackOverflowError* exception.
Although Java specs says that extreme caution is advised when having a map
contain itself as a value, JavaFlow should not do any assumption about data it
needs to work with and should be able to deal with such a situation.
The hash code is computed in
{{org.apache.commons.javaflow.utils.ReflectionUtils.getClassName(final Object
o)}} which is called e.g. from
{{org.apache.commons.javaflow.bytecode.Stack.pushObject(Object o)}}.
Possible workaround is to disable debug messages.
