community master is failing to package due to jps-standalone-builder

I have experienced this for quite a few days now, so I thought I'd bring it up:

<pre>
[java] Build intellij-core
[java] [mkdir] Created dir: /proj/jetbrains/community-clean/out/artifacts/core
[java] [jar] Building jar: /proj/jetbrains/community-clean/out/artifacts/core/___tmp___/_0/intellij-core.jar

[java] BUILD FAILED

and this is still true as of master at 259bd8f3
