Question: What is exactly not working ? Tools->Organzie Macros -> JavaScript|Beanshell|Python pops up a message boxes that no JRE is installed but then the Dialog is displayed (see http://www.openoffice.org/issues/show_bug.cgi?id=37020)<br />

== Java detection in OpenOffice.org 2 and StarOffice 8 ==<br />
<br />
=== Which Java will be used? ===<br />
<br />
[[StarOffice]] tries to detect the newest Java version installed. StarOffice only detects Sun Java versions, while OpenOffice.org also detects Java versions from other vendors.<br />
<br />
When using versions from different vendors, the numbering system might be different so maybe not the newest version is used. You can change the Java version in StarOffice via tools/options/Java.<br />
<br />
On [[GNOME]], if AT tool support is enabled, StarOffice will use that latest version where the [[Java Access Bridge]] is enabled.<br />
<br />
=== When is Java detection done? ===<br />
<br />
On Windows, detection is done the first time Java is used. On Linux/Solaris, detection is done the first time a user starts StarOffice.<br />
<br />
=== How can I reset the Java configuration? ===<br />
<br />
The configuration is stored in<br />
<br />
< staroffice-config > /user/config/javasettings_ < platform > .xml<br />
<br />
Just delete this file if you want StarOffice to detect again.<br />
The Java configuration file cannot be modified manually. The data format<br />
is not specified and may change anytime without further notice.<br />
Don't try to modify that file to change the Java version. The < location ><br />
and < version > entries are only for 'documentation', the Java version is<br />
accessed via the < vendorData > , which is binary.<br />

<div>== Known areas for improvement ==<br />
<br />
=== system issues ===<br />
* Linux / Linking - relocation processing is very [http://go-oo.org/~michael/performance.odp slow] two possible ways to fix that<br />
** re-ordering symbol & elf hash tables to improve cache locality, lots of good & simple ideas here.<br />
** -Bdirect implementation [http://sourceware.org/ml/binutils/2005-10/msg00436.html] - gaining little traction.<br />
* Linux / I/O scheduling & pre-loading is poor<br />
<br />
=== General I/O & memory issues ===<br />
* Config mgr - scattered files<br />
* UI configuration - tons of scattered files<br />
* .rdb files - loads of empty space, mmap + random access pattern<br />
<br />
== Helpful tooling ==<br />
<br />
* [[cold-start-simulator|Linux/cold-start]] simulator<br />
* [[relocstat]] - dump relocation data<br />
* [http://tools.openoffice.org/profiling/profiling-howto.html RTL_LOGFILE] - export RTL_LOGFILE=/tmp/foo<br />
* [[valgrind]] - debug / trace memory usage<br />
* [[speedprof]] - a quick / hackish sampling full-stack-trace profiler & visualisation tool<br />
<br />
== Approaches being worked on == <br />
* Config refactor - reduce seeks/files, better caching <br />
* [[Disk Access]]<br />
* -Bdirect linking<br />
* FIXME - Malte - we should really have your list embedded here ...<br />
