Hi folks!
Sorry for the crosspost to 2 lists, but this info might be interesting for both
of you.
I saw that servicemix and geronimo both still use javassist-3.7.
I would strongly recommend upgrading all projects (where possible) to the
newest version 3.12.0.GA. These old versions of javassist may create huge mem
leaks [1][2][3].
Sadly 3.12.0.GA is not yet uploaded to maven.central, but this is work in
progress (will take a few weeks since Pete Muir is on vacation).
The artifact is available in the JBoss.brew repo:
<repositories>
<!-- TODO: this must get removed once javassist is released to
maven.central -->
<repository>
<id>jboss.brew</id>
<url>http://repository.jboss.org/maven2-brew</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
</repositories>
To show the difference:
With the old javassist version, my real world app lost more than 1MB
PermGenSpace each page hit (due to heavy use of interceptors and stuff). This
is gone with javassist-3.12.0.GA.
LieGrue,
