When dev-java/ant-core-1.8.1 failed to build I noticed java fail to run if not given option to limit heap size. Google suggests it happens because on system with 4GB or more RAM java try to start in -server mode. Sadly, but looks like icedtea VM doesn't support environment variable like JAVA_OPTS, so I can't work around this issue by just `export JAVA_OPTS="-client"`. home ~ # java-config-2 -L The following VMs are available for generation-2: *) IcedTea6-bin 1.9.1 [icedtea6-bin] home ~ # java -version Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. home ~ # java -server -version Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. home ~ # java -client -version java version "1.6.0_20" OpenJDK Runtime Environment (IcedTea6 1.9.1) (Gentoo build 1.6.0_20-b20) OpenJDK Client VM (build 19.0-b06, mixed mode) home ~ # java -Xmx1024m -version Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. home ~ # java -Xmx512m -version java version "1.6.0_20" OpenJDK Runtime Environment (IcedTea6 1.9.1) (Gentoo build 1.6.0_20-b20) OpenJDK Server VM (build 19.0-b06, mixed mode) home ~ # free total used free shared buffers cached Mem: 4137388 3008040 1129348 0 505076 1134520 -/+ buffers/cache: 1368444 2768944 Swap: 4200956 60476 4140480 home ~ # ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 32320 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 32320 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited Also I should note SOMETIMES java success to run even in -server mode on my system: home ~ # for i in $(seq 1 100); do java -version &>/dev/null && echo ok; done | wc -l 12 home ~ # for i in $(seq 1 100); do java -client -version &>/dev/null && echo ok; done | wc -l 100 Reproducible: Always Steps to Reproduce: 1. java -version 2. 3.

I've just tried also dev-java/sun-jdk-1.6.0.22. To emerge it I had to patch sun-jdk-1.6.0.22.ebuild: - "${S}"/bin/java -server -Xshare:dump || die + "${S}"/bin/java -server -Xmx256m -Xshare:dump || die To use it I had to edit /opt/sun-jdk-1.6.0.22/jre/lib/i386/jvm.cfg to force client VM: --client IF_SERVER_CLASS -server --server KNOWN +-client KNOWN This way ant-core (originally failed package) emerged successfully. If anybody think I should open another bug for sun-jdk let me know.
I think it would be worth opening another bug for sun-jdk, thanks. Assigning this one to java team to take a look.
Keeping in mind only option to have java working is fixing jvm.cfg, I think it worth adding CONFIG_PROTECT="/opt/icedtea6-bin-1.9.7/jre/lib/i386/jvm.cfg" to some file in /etc/env.d/ in this ebuild. Bad thing is this file located in "icedtea6-bin-1.9.7" directory, i.e. CONFIG_PROTECT helps while re-emerging same package version but installing another version result in losing config changes. Probably this file should be moved to /etc/. BTW, google search for "Could not reserve enough space for object heap" return many results, but no solutions. This issue is same for both icedtea6 and sun-jdk and happens on machines with 4GB+ RAM because both javas try to run as -server on such systems. Looks like both upstreams aware about issue, but there no fix yet. First workaround with adding "-Xmx" option doesn't really useful, because this issue happens while emerging packages (like ant or cmake) when we can't control java options. Second workaround with editing jvm.cfg not really useful until there will be way to protect changes in this config.
Even so this one is older the other one is more informative. *** This bug has been marked as a duplicate of bug 389751 ***
