> increase maxmemory for unit tests
> ---------------------------------

> Key: LUCENE-1414
> URL: https://issues.apache.org/jira/browse/LUCENE-1414
> Project: Lucene - Java
> Issue Type: Bug
> Components: Build
> Affects Versions: 2.4, 2.9
> Reporter: Michael McCandless
> Assignee: Michael McCandless
> Priority: Minor
> Fix For: 2.9
>

> We have some unit tests that require a fair amount of RAM. But, sometimes
> the JRE does not give itself a very large max heap size, by default. EG on a
> Mac Pro with 6 GB physical RAM, I see JRE 1.6.0 defaulting to max 80 GB and
> it always then hits this exception during testing:
> [junit] Testcase: testHugeFile(org.apache.lucene.store.TestHugeRamFile):
> Caused an ERROR
> [junit] Java heap space
> [junit] java.lang.OutOfMemoryError: Java heap space
> [junit] at java.util.Arrays.copyOf(Arrays.java:2760)
> [junit] at java.util.Arrays.copyOf(Arrays.java:2734)
> [junit] at java.util.ArrayList.ensureCapacity(ArrayList.java:167)
> [junit] at java.util.ArrayList.add(ArrayList.java:351)
> [junit] at org.apache.lucene.store.RAMFile.addBuffer(RAMFile.java:69)
> [junit] at
> org.apache.lucene.store.RAMOutputStream.switchCurrentBuffer(RAMOutputStream.java:129)
> [junit] at
> org.apache.lucene.store.RAMOutputStream.writeBytes(RAMOutputStream.java:115)
> [junit] at
> org.apache.lucene.store.TestHugeRamFile.testHugeFile(TestHugeRamFile.java:68)
> The fix is simple: add maxmemory=512M into common-build.xml. I'll commit
> shortly.
