and subject line closing remaining openjdk-6 bugs

Package: openjdk-6
Severity: normal
Java uses 1/4 ( MaxRAMFraction [1]) of the _physical_ memory as heap
(Arguments::set_heap_size() [2]). If there is any limit pushing java
below this, for example a ulimit, it will fail. The failure could also
be cause in a virtualised situation for example using OpenVZ where the
kernel will report the total memory, but the partition has a limit of
less than 1/4 of that.
The only reasonable workaround is to pass the "-Xmx" option whenever
you run Java, but this isn't set when installing the
openjdk-6-jre-headless package, so even setting that package up can
fail with:
Could not create the Java virtual machine.
Error occurred during initialization of VM
Could not reserve enough space for object heap
I'm not sure of the best course of action to solve this - it seems like
the nicest thing would be to look at the limit using the ulimit
interface and reduce the default to a bit less than that (to allow for
things other than the heap itself).

Hi,
openjdk-6 was last released with Debian 7.0 (wheezy), which had its LTS
support end nearly a year ago and which has now been archived.
I'm therefore closing the remaining openjdk-6 bugs, assuming they are no
longer relevant for newer (and still supported) openjdk releases.
