[jira] Commented: (DIRSTUDIO-585) Do not modify the current
thread's ClassLoader; or reset it afterwards
[ https://issues.apache.org/jira/browse/DIRSTUDIO-585?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12842646#action_12842646 ]
Stefan Seelmann commented on DIRSTUDIO-585:
-------------------------------------------
Thanks Karsten for the proposed workaround.
I think we should get rid of the XMLEncoder at all.
In Utils it is used to store some preferences and I was to lazy to build our own Object<->XML mapping. I'll add your proposed workaround here.
In BrowserConnectionManager it is only used for backward compatibility to be able to convert old connections.xml format. I think we use the new file format since 1.0. So the code in this class should never be executed. Let's remove the legacy code with Studio 2.0

> Key: DIRSTUDIO-585
> URL: https://issues.apache.org/jira/browse/DIRSTUDIO-585
> Project: Directory Studio
> Issue Type: Bug
> Components: studio-ldapbrowser
> Affects Versions: 1.4.0, 1.5.0
> Reporter: Karsten Baensch
>
> Hi,
> in BrowserConnectionManager.load
> and in
> Utils.serialize / deserialize
> we recognized that the ClassLoader is modified without conserving / resetting it to the previous one at the end.
> This conflicted with our class loading mechanisms ... streaming from our own class store.
> As a quick fix for testing, we could do for example the following; however, this is not a real solution:
> public static String serialize( Object o )
> {
> String s = null;
> Thread cur_thrd = Thread.currentThread(); //patch reset current class loader
> ClassLoader cur_thrd_cl = cur_thrd.getContextClassLoader();
> try{
> cur_thrd.setContextClassLoader( Utils.class.getClassLoader() );
> ByteArrayOutputStream baos = new ByteArrayOutputStream();
> XMLEncoder encoder = new XMLEncoder( baos );
> encoder.writeObject( o );
> encoder.close();
> s = LdifUtils.utf8decode( baos.toByteArray() );
> }finally{
> cur_thrd.setContextClassLoader(cur_thrd_cl);
> }
> return s;
> }
> => Is there a better way?
> Thanks and regards,
> Karsten
