Description
ADDITIONAL SYSTEM INFORMATION :
java version "1.8.0_65"

A DESCRIPTION OF THE PROBLEM :
In some cases, jvm does constant metaspace gc when allocated metaspace size reached MaxMetaspaceSize

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
java -XX:+PrintGCDetails -XX:InitialHeapSize=512m -XX:MaxHeapSize=512m -XX:+PrintGCDateStamps -XX:MetaspaceSize=12m -XX:MaxMetaspaceSize=50m -Xloggc:gc.log -verbose:gc -Dfile.encoding=UTF-8 -classpath "C:\Users\K5C160\projects\other\classloader-leak\sample\target\classes" com.eguller.metaspace.App "C:\Users\K5C160\projects\other\classloader-leak\sample\arbitrary.jar"

I gave following inputs to program below. (com.eguller.metaspace.App)
Load/Unload: 6000
Load/Unload: 500
Load/Unload: 300
Load/Unload: -1000
Load/Unload: 200
Load/Unload: 100
Load/Unload: 200
Load/Unload: 300

My observation if committed metaspace memory hits to max size (and also if gc can decrease used memory because of unloaded classes), metaspace gc goes into infinite loop.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Either jvm process should terminate with an out of memory error, or jvm could recover and open some space after garbage collection and application should continue to run. In this case application freezes because of constant major GCs.

A few more things I want to mention regarding to metaspace. In metasapce gc log, reserved space is misleading. Even if I set  -XX:MaxMetaspaceSize=50m, reserved space is shown as 1085440K. It does not correlate with anything which is set by user and I think it is misleading. 
[Metaspace: 16206K->16206K(1085440K)]

Another point regarding to metaspace related out of memories, committed space is taken into account in case of out of memories. Even if used space is quite low, and there is more space to use, jvm goes out of memory if committed space reaches to max size and  cannot be increased.
For example in this case metaspace size is 12mb and max size is 50mb. And by default min free ratio is %40.
So after each grow and allocate, free metaspace size will increase. For 50mb max metaspace it is possible to get out of memory around 17-24mb used space. With default configuration around %60 of memory will kept empty. Why jvm cannot utilize this free instead of going out of memory ? 
ACTUAL -
I kept application open for 10-15 minutes, it kept doing full GC instead of terminating. Similar error happened in production also.

Could not reproduce.

Hi Thomas, Below my answers inlined > - reported on 8u65 (by submitter) > - "last worked with 8u192" (assuming this means that the VM did not show the issue with that version) (submitter?) This is an issue with our bugreporting application, that should not have been allowed submitter to enter regression information if lower versions are selected. usually we correct that at our end, in this case i missed that. I have updated description to reflect that change. >- "verified" with 8u65 and 8u212 (without the attached reproducer; "verified" means that the problem is in 8u65 and 8u212?) I could not able to reproduce the issue in any version. Verified sounds bit confusing here, i verified (I am able to run the program as expected) problem by executing test case and could not reproduce. >- asked for 13-ea reproduction (you were not able to reproduce?) Yes, I am not able to reproduce the issue. >So summarizing, the problem exists in 8u65, but somewhere betwee that and 8u192 it had been fixed (worked with 8u192), and did not work with 8u212 again? This is not the case, by above clarifications. I executed the attached program by reducing the various arguments (InitialHeapSize MaxHeapSize MetaspaceSize MaxMetaspaceSize) but could not reproduce the issue. Thinking that it could be an corner case when committed metaspace memory hits to max size (and also if gc can decrease used memory because of unloaded classes), metaspace gc goes into infinite loop, kept as an issue for further review. Reproducer status can be found with our unique labels used by our team (reproducer-no indicate we are not able to reproduce/no reproducer) Please let me know for any further clariffication and sorry for invalid regression information. Thanks, Fairoz

[~fmatte]: I am a bit confused about the state of this issue. From what I can gather about affected versions from the bug report is the following: - reported on 8u65 (by submitter) - "last worked with 8u192" (assuming this means that the VM did not show the issue with that version) (submitter?) - "verified" with 8u65 and 8u212 (without the attached reproducer; "verified" means that the problem is in 8u65 and 8u212?) - asked for 13-ea reproduction (you were not able to reproduce?) So summarizing, the problem exists in 8u65, but somewhere betwee that and 8u192 it had been fixed (worked with 8u192), and did not work with 8u212 again? That sounds strange to me.
