<h1>AspectJ 1.5.1 Readme</h1>
<p>This release is primarily a bug fix and performance / memory usage release.
Over 70 fixes and enhancements have been incorporated since 1.5.0, you
can see the list through this
<a href="https://bugs.eclipse.org/bugs/buglist.cgi?query_format=advanced&product=AspectJ&target_milestone=1.5.1&bug_status=RESOLVED&bug_status=VERIFIED&bug_status=CLOSED"/>
bugzilla query</a>.
</p>
<p>
AspectJ 1.5.1 has significantly lower memory usage than AspectJ 1.5.0, especially when
building inside of AJDT. The improvements are also noticeable when batch building with Ant,
or when load-time weaving. Batch building a project with over 1000 source files with
both AspectJ 1.5.1 and AspectJ 1.5.0 shows a 16% reduction in peak memory usage,
and an 8% reduction in heap consumed by temporary objects. The AspectJ 1.5.1 compiler
integrated into AJDT gives memory savings of at least 50%. The greater savings in
the AJDT environment are due to improvements in areas such as structure model
generation that are not exercised in a batch build.
