> Recently we upgraded from[Axis2-1.4.1 on Websphere-7.0] to [Axis2-1.6.2 on Websphere-8.5]. And the same application code start giving an intermittent exception. The stacktrace of the exception can be found at the end of the description.
> Analysis -
> The creation of these system properties is the root cause of the issue.
> http.proxyHost and http.proxyPort
> These system porperties are created with non-null but empty string "" values.
> We find that our application has no logic to create these properties. These properties probably created by a 3rd party library or websphere server.
> Workaround -
> We write a code to remove these system properties (System.clearProperty()) just before the flow goes to Axis2 part of the application.
> We cannot write this code during application startup as these properties are created intermittently when the application is running for few days and the exception appears again.
> Recommendations -
> In this axis code
> package org.apache.axis2.transport.http.util
> class HTTPProxyConfigurationUtil
> method configure(MessageContext messageContext,
> HttpClient httpClient,
> HostConfiguration config)
> the exception appears at the following line of code -
> String port = System.getProperty(HTTP_PROXY_PORT);
> if(port != null) {
> proxyPort = Integer.parseInt(port);
> }
> This is because the non-null but empty-string ("") valued key HTTP_PROXY_PORT, results in NumberFormatException.
> Can we please add an empty-string value check in the "if" condition ?
> Adding further thse empty-string valued keys, both host and port, might overwrite the correct values built from axis2.xml. Hence we can apply the same checks to both of the system properties - host and port - if conditions.
