Lars Hofhansl commented on HBASE-5261:
--------------------------------------
I found that in order to build HBase with OpenJDK7 I need to make this change:
{code}
--- pom.xml (revision 1358499)
+++ pom.xml (working copy)
@@ -395,6 +395,9 @@
<target>${compileSource}</target>
<showWarnings>true</showWarnings>
<showDeprecation>false</showDeprecation>
+ <compilerArguments>
+ <Xlint:-options/>
+ </compilerArguments>
</configuration>
</plugin>
{code}
That suppressed the following warning (which maven fails to parse and hence
errors out):
bq. warning: [options] bootstrap class path not set in conjunction with -source
1.6
G1 is supposed to be viable from OpenJDK7u4 onwards.

> We need to make sure that HBase compiles and works with JDK 7. Once we verify
> it is reasonably stable, we can explore utilizing the G1 garbage collector.
> When all deployments are ready to move to JDK 7, we can start using new
> language features, but in the transition period we will need to maintain a
> codebase that compiles both with JDK 6 and JDK 7.
