[cross-project-issues-dev] Fw: [eclipse-pmc] Request approval to fix bug

[John Arthorne <John_Arthorne@xxxxxxxxxx>]

A bug was discovered this week in the Helios
SR2 build of Java development tools (JDT). In rare cases this bug caused
code to be incorrectly identified as dead code, and removed by the compiler.
This bug will be fixed in our Helios SR2 RC4 contribution next Monday.
Also, we produced a patched version of the platform base builder containing
the fixed JDT core. We recommend projects use a fixed build of JDT to perform
their final SR2 builds next week, if possible.

See the thread below for further details.

The org.eclipse.releng.basebuilder with
the new jdt core  is in the patched_361builder branch of /cvsroot/eclipse
and tagged as r36x_v20110209.  I'm running a test build with this
new builder and will schedule a rebuild for later today.

We've discussed this at today's PMC call: given the severity of the 
problem, we will provide a patched 3.6.1 base builder and do another 
Eclipse SDK build with the new builder.

Does this have an impact on software being built at Eclipse ... in other
words, should the Helios SR2 train make sure that they use a Platform 
3.6.2 Basebuilder such that the compiler generates correct code ?

Thanks,
Martin

+1. This is really bad and the fix is not risky.

Hi, 

A bad bug has been discovered which has an impact at runtime. The compiler
is tagging some statement as dead code and therefore optimize them out
of 
the code generation. This is related to a bogus diagnosis for null 
analysis. 
A fix is ready and has been released for 3.7M6. 
We request approval to release it for 3.6.2 as well.
