Hi Alan, Xueming, build-ers,
I'd like you to do a code review. I've finally figured out why fastdebug jdk occasionally gives InternalError in the zip code. Exception in thread "main" java.lang.InternalError at java.util.zip.Inflater.init(Native Method) at java.util.zip.Inflater.(Inflater.java:101) at java.util.zip.ZipFile.getInflater(ZipFile.java:448) It's because: - jdk changed structure size of zstream struct - making jdk zlib incompatible with stock zlib - as a result of which, it is imperative to keep jdk zlib sequestered from system zlib - so need to not export zlib symbols from libzip.so - so need to tell makefiles to use linker script unconditionally http://cr.openjdk.java.net/~martin/webrevs/openjdk8/hide-zlib/ <http://cr.openjdk.java.net/%7Emartin/webrevs/openjdk8/hide-zlib/>
