[news.eclipse.technology.iam] Re: Release candidate 0.9.0 at Q4E

[marek-romanowski@xxxxx (Marek Romanowski)]

I've dumped JVM memory on OutOfMemoryError and started to analyze it with 
Eclipse Memory Analyzer. I think there is some problem with MavenLog 
class. One of instances points to a String 275MB big... Connections go 
like this:

MavenEventStore -> CircularFifoBuffer -> Object[10000] -> MavenLog -> 
String -> char[137022158]

So it looks like MavenEventStore stores logs in CircularFifoBuffer. CFB 
has got array of logs (array size: 10000). Array holds reference to a 
MavenLog which references enormous String (137022158 characters). This 
String starts with: "  (f) classpathElements = [" - after this goes 
classpath elements from my project; two first chars are whitespaces.

I think this take place only while plugin enables maven dependency 
management. Maybe when I'm enabling it for 50+ projects at one operation, 
this log is concatenated between all of them?


I hope this will help you,
Marek.
