Description

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.
