I remember Pavel suggested refactoring class.hquite some time ago...if it is being done, we should add this to the Wiki as a ability/modularization item in the DRLVM dev list. Probably this is finished but not applied yet. I've found HARMONY-1558 with patches that do this cleanup. -- Gregory Shimansky, Intel Middleware Products Division

Yeap.
The following addresse both your issues.
class GCv5Magics {

else {

I like this approach! :)

[drlvm][eclipse compiler] the test compiled with ECJ fails on drlvm
Hi all, after classlib build system has switched to use ECJ, one test in swing module started to fail on drlvm (win/linux). Actually the failure is not related to swing functionality. I've filed JIRA issue https://issues.apache.org/jira/browse/HARMONY-1931 and attached a simple test to reproduce the failure. All interested parties are welcome to look at this issue! -- Thanks, Elena

Doesn't it mean that is you specified something in -Dvm.em_dll on command line that System.getProperty would return non null value, and then you shall use System.load instead of System.loadLibrary? That is if you change gc to em in the code above. Gregory, I have completely forgotten about System.load() and System.loadLibrary() differences. So the problem is solved and I have even tested the code :) -- Mikhail Fursov
Re: [drlvm] Using JNI methods in VM's components.
Pavel, I'm sorry I do not understand what the replacement do you mean? I said that only about a part of a component could be written in Java (e.g. EM, helpers), but not the whole component...
