On Win7, I'm getting compilation failures on branch_4x and trunk, under Maven
(2.2.1 and 3.0.4) and IntelliJ (11.1.3). Under Ant (1.8.2), compilation
succeeds. I've tried Oracle JDK 1.6.0_21 and 1.6.0_34, both 64-bit, and both
behave the same (success under Ant, failure under Maven and IntelliJ). Maven
and IntelliJ compilation succeeds using Java7 (Oracle 1.7.0_01 64-bit).
AFAICT, the failures seem related to Mike McCandless's LUCENE-3892
(BlockPostingsFormat) commit yesterday; o.a.l.util.packed.BulkOperation looks
like the common denominator. This class is a huge file (31k lines) generated
by gen_BulkOperation.py.
On Linux (Debian Squeeze x64_86) I get the same compilation failures under
Maven 2.2.1 using either Oracle JDK 1.6.0_24 or OpenJDK 1.6.0_18. However, the
ASF Jenkins Maven trunk build succeeded today at r1376102 (Mike's commit was
r1375495) - this is FreeBSD, with Maven 2.2.1 and OpenJDK 1.6.0_32. I'm
building OpenJDK 6 b25 on Linux from the source bundle now (not sure what the
Oracle-compatible version number is), and once it's finished I'll give it a try
and report back.
I tried increasing the compiler's max memory under both systems, to 1GB, but
compilation still failed.
I was able to get IntelliJ compilation to succeed, using the "Javac in-process"
compiler option, as well as using the Eclipse compiler option. I wasn't able
to get compilation to succeed under Maven, though; upgrading
maven-compiler-plugin to the latest version (v2.5.1) didn't help.
I tried to get Ant to fail by adding fork="yes" to the <javac> invocation in
lucene/common-build.xml, but it still succeeds.
Here are the errors from the Maven 2.2.1 compilation output under trunk
lucene/core/ using Oracle JDK 1.6.0_34:
