Nullpointer in PacProxySelector
Kogs opened this issue · comments
We added the proxy vole Libary to an Software.
When the Customer tried to test it he get the following exception while doing some http request.
The code to setup Proxy Vole looks like this:
```
private static void checkProxies() {
logger.info("Start proxy search");
try {
ProxySearch proxySearch = ProxySearch.getDefaultProxySearch();
proxySearch.addStrategy(Strategy.OS_DEFAULT);
proxySearch.addStrategy(Strategy.JAVA);
proxySearch.addStrategy(Strategy.BROWSER);
ProxySelector myProxySelector = proxySearch.getProxySelector();
ProxySelector.setDefault(myProxySelector);
if (myProxySelector != null) {
List<Proxy> proxies = myProxySelector.select(new URI(RestUtil.BASE_URL));
for (Proxy proxy : proxies) {
logger.info("Proxy type {}", proxy.type());
InetSocketAddress addr = (InetSocketAddress) proxy.address();
if (addr == null) {
logger.info("No Proxy Address found");
} else {
logger.info("Proxy host {} {}", addr.getHostName(), addr.getPort());
}
}
} else {
logger.info("No Proxy Settings found");
}
} catch (Exception e) {
logger.error("Failed to search Proxies", e);
}
}
```
This logs:
Proxy type DIRECT
No Proxy Address found
