Description
Since the change:
changeset: 2059:3582bf76420e
user: coleenp
date: Thu Jan 27 16:11:27 2011 -0800
summary: 6990754: Use native memory and reference counting to implement SymbolTable
We now print symbol info during SymbolTable::unlink()
if (PrintGCDetails) {
gclog_or_tty->print(" [Symbols=%d size=%dK] ", total,
(memory_total*HeapWordSize)/1024);
}
This has the effect of changing the format for GC output.
G1 example:
[GC remark [Symbols=8043 size=310K] , 0.0008960 secs]
CMS example:
[GC [ParNew (promotion failed): 27003K->29504K(29504K), 0.0998240 secs][CMS [Symbols=8051 size=310K] : 152035K->32457K(229376K), 0.1605210 secs] 165353K->32457K(258880K), [CMS Perm : 2609K->2608K(21248K)], 0.2608550 secs] [Times: user=0.37 sys=0.03, real=0.26 secs]
It will also be called in a Full GC, changing the output there as well.
