some Eclipse compiler warnings

[Joerg Heinicke <jo...@gmx.de>]

javaflow block:

The private field Continuation.parent is never read locally 
src/blocks/javaflow/java/org/apache/cocoon/components/flow/java/Continuation.java
line 30
=> parent is only needed in the constructor => remove the field

The private field FormInstance.submitId is never read locally
src/blocks/javaflow/java/org/apache/cocoon/forms/flow/java/FormInstance.java
line 50
=> do not really know

The local variable form is never read
src/blocks/javaflow/java/org/apache/cocoon/forms/flow/java/FormInstance.java
line 97
=> this.form = formMgr.createForm(formDefinition);
=> what about this.form vs. formWidget ?? => remove formWidget


slide block:

The private method getChildByPath(String) from the type SourceDTO is 
never used locally
src/blocks/slide/java/org/apache/cocoon/components/source/SourceDTO.java
line 327
=> remove it


webdav block:

The private field WebDAVRepositoryPropertyHelper.manager is never read 
locally
src/blocks/webdav/java/org/apache/cocoon/components/repository/impl/WebDAVRepositoryPropertyHelper.java
line 49
=> remove manager, don't implement Serviceable, Disposable ??

The private field WebDAVRepositoryPropertyHelper.credentials is never 
read locally
src/blocks/webdav/java/org/apache/cocoon/components/repository/impl/WebDAVRepositoryPropertyHelper.java
line 55
=> do not really know

The private field WebDAVRepositoryTransactionHelper.manager is never 
read locally
src/blocks/webdav/java/org/apache/cocoon/components/repository/impl/WebDAVRepositoryTransactionHelper.java
line 39
=> remove manager, don't implement Serviceable, Disposable ??

The private field WebDAVRepositoryVersioningHelper.manager is never read 
locally
src/blocks/webdav/java/org/apache/cocoon/components/repository/impl/WebDAVRepositoryVersioningHelper.java
line 40
=> remove manager, don't implement Serviceable, Disposable ??

The private field WebDAVRepositoryVersioningHelper.credentials is never 
read locally
src/blocks/webdav/java/org/apache/cocoon/components/repository/impl/WebDAVRepositoryVersioningHelper.java
line 46
=> do not really know

The local variable sourceURL is never read
src/blocks/webdav/java/org/apache/cocoon/components/webdav/WebDAVUtil.java
line 79
=> I guess the statement itself (new HttpURL(uri);) is needed for 
enforcing errors, but not the local variable => remove it ?

Any comments??
