My concern with using g1 is solely based on finding this. Does anyone have any information on this?
https://wiki.apache.org/lucene-java/JavaBugs#Oracle_Java_.2F_Sun_Java_.2F_OpenJDK_Bugs "Do not, under any circumstances, run Lucene with the G1 garbage collector. Lucene's test suite fails with the G1 garbage collector on a regular basis, including bugs that cause index corruption. There is no person on this planet that seems to understand such bugs (see https://bugs.openjdk.java.net/browse/JDK-8038348, open for over a year), so don't count on the situation changing soon. This information is not out of date, and don't think that the next oracle java release will fix the situation."
