[Bug 1241926] Re: Giant Bug: Cannot run java with a virtual mem limit (ulimit -v)

[Martin Babutzka]

* I wanted to add that I dont want to ultimatively blame Java for this.
There is aweseome software out there written in Java. But this VM
behavior really did cost me a lot of time and nerves.

Title:
  Giant Bug: Cannot run java with a virtual mem limit (ulimit -v)

Status in openjdk-7 package in Ubuntu:
  Confirmed

Bug description:
  $ java
  Usage: java [-options] class [args...]
             (to execute a class)
     or  java [-options] -jar jarfile [args...]
             (to execute a jar file)
  [...]
  $ ulimit -v 2097152
  $ java
  #
  # There is insufficient memory for the Java Runtime Environment to continue.
  # pthread_getattr_np
  # An error report file with more information is saved as:
  # /home/moritz/hs_err_pid16051.log

  This is no reason why java should try to allocate more than 2 GB of
  RAM for diplaying a simple help message. If it does need much memory,
  it should inspect existng limits to make sure it doesn't try to
  allocate more than the resource limit.

  It's very inconvenient not to be able to run java just because of
  (very generous) per user ulimits.
