This issue concerns builds of jigsaw/m2, the staging forest for the Project Jigsaw milestone that is the modular image.

Currently it is not possible to run the langtools tests in JPRT. Many of the javadoc and doclint tests fail with OOME. JPRT eventually kills the jobs as it takes too long.

JPRT runs the tests via langtools/test/Makefile. The make file seems to run the tests with -samevm and -vmoption:-Xmx768m. I've tried increasing the heap size to 1GB but it doesn't make a difference. On the other hand, running the tests with -agentvm -vmoption:-Xmx512m works just fine.

This bug is submitted to investigate this issue, just in case we have a leak or other issue with the javac support for jimage.
