error dump from java

Hi,

We run tomcat on openjdk8, and see crashes on servers with reasonable load reqularly, several times a week per server.

It occurs on about a dozen servers. The servers having troubles are all used with a reasonable load. Servers with no, or very low, loads are not in trouble.

It seems the problems are always in "Java2D Disposer". Can it be a problem with IcedTea?

We run tomcat7.

$ pkg info -drx openjdk8
openjdk8-8.51.16
Depends on     :
	libXtst-1.2.2_3
	libXrender-0.9.8_3
	libXi-1.7.4_1,1
	libXext-1.3.3_1,1
	libX11-1.6.2_3,1
	libXt-1.1.4_3,1
	fontconfig-2.11.1,1
	dejavu-2.35
	freetype2-2.6_1
	javavmwrapper-2.5
	java-zoneinfo-2015.e_1
	giflib-5.0.6
	alsa-lib-1.0.29

10.1-RELEASE-p15

We build all packages, using poudriere, with OPTIONS_UNSET=  NLS X11.

Any ideas? Getting a core dump seems impossible, dunno why.

This is fixed upstreams in https://bugs.openjdk.java.net/browse/JDK-8132985

I suggest adding the attached patch to java/openjdk8, since the bug is easily reproducible, and at least for us it was a really big problem until we added the patch.
