Hello,
I've downloaded the Java 8 early access build for Linux 64bits.
I've made some simple tests with JMeter (2.12-SNAPSHOT) and try to build
JMeter with Java 8.
I've found these issues:
On JMeter startup, we have these warnings:
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=64m;
support was removed in 8.0
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option
MaxPermSize=128m; support was removed in 8.0
Meaning that Java 8 don't offer to define the permanent memory size?
On JMeter build:

Where I can find the documentation on the changes about the error "name
clash"? What is the best way to fix this errors?
I will make other tests (load tests) with a JMeter builds with Java 6
and running on Java 8.

Hi,
I am from the OpenJDK Quality Group at Oracle. I am working with Open
Source projects
that are testing JDK 8 Early Access builds (either those published by
Oracle <https://jdk8.java.net/download.html>, or their own)
and I would like to encourage more of it to happen.
I am looking for a contact person who is interested in working with me
, sharing your test
experiences and any issues uncovered by testing JMeter with JDK 8 EA
builds. I expect
this will be of benefit to both communities.
We are now very late in the release cycle of JDK 8 , issues found late
may be postponed to
an Update Release.
Rgds, Rory
