Review Comment:
Yes that is right, I noticed this while doing different tests but forgot to
push the changes. Pushing the commit now.
> Various memory usage improvements
> ---------------------------------
>
> Key: MNG-7899
> URL: https://issues.apache.org/jira/browse/MNG-7899
> Project: Maven
> Issue Type: Improvement
> Components: Design, Patterns & Best Practices, Embedding,
> General, Logging
> Affects Versions: 4.0.0-alpha-2
> Reporter: sebastien
> Priority: Major
>
> Some optimisations can be applied to the code to reduce the use of temporary
> objects.
> Typical improvements identified are:
> * reduce scope of temporary objects creation to avoid creating when not
> needed. Example :
> {code:java}
> public String toString() {
> StringBuilder sb = new StringBuilder(512);
> if (isEmpty()) {
> return "empty";
> }
> for (MetadataGraphVertex v : vertices) {
> .....{code}
> can be replaced by
> {code:java}
> public String toString() {
> if (isEmpty()) {
> return "empty";
> }
> StringBuilder sb = new StringBuilder(512);
> for (MetadataGraphVertex v : vertices) {
> .....{code}
> * Reuse StringBuilder objects in loops by setting its length to zero
> * Use the StringBuilder.append() with index to avoid String.substring().
> Example:
>
> {code:java}
> int idx = resourceName.lastIndexOf('/');
> buffer.append(idx < 0 ? resourceName : resourceName.substring(idx + 1));
> {code}
> can be replaced by
>
> {code:java}
> int idx = resourceName.lastIndexOf('/');
> if (idx < 0) {
> buffer.append(resourceName);
> } else {
> buffer.append(resourceName, idx + 1, resourceName.length());
> } {code}
>
>
> * Replace dynamic string creation static constants when possible
> * Avoid creating temporary strings with + operator when the final
> destination can be used instead, like PrintStream.print() method
> * Avoir using StringBuilder.append() method and util method MessageUtils.a()
> when the final destination can be used instead, like PrintStream.print()
> method
>
