远程byteman代理报告错误

Question

我需要一点帮助来理解这两个规则的问题。

RULE inefficient FilterOutputStream write trace
CLASS java.io.FilterOutputStream
METHOD write( int )
AT RETURN
IF TRUE
DO traceStack("*** Slow write calls ***", 10)
ENDRULE

RULE inefficient FilterInputStream read trace
CLASS java.io.FilterInputStream
METHOD read( )
AT RETURN
IF TRUE
DO traceStack("*** Slow read calls ***", 10)
ENDRULE

运行bmcheck显示

Checking rule inefficient FilterOutputStream write trace against class java.io.FilterOutputStream
Parsed rule "inefficient FilterOutputStream write trace" for class java.io.FilterOutputStream
Type checked rule "inefficient FilterOutputStream write trace"
Checking rule inefficient FilterInputStream read trace against class java.io.FilterInputStream
Parsed rule "inefficient FilterInputStream read trace" for class java.io.FilterInputStream
Type checked rule "inefficient FilterInputStream read trace"
TestScript: no errors

当提交规则时，我看到这个错误

$ jboss/byteman/byteman-download-4.0.17/bin/bmsubmit.sh -u /somewhere/scripts/InefficientIOStreamHandling.btm

在jvm的控制台中有这个

$ TransformListener() : handling connection on port 9091
$

还有什么需要我检查的吗?

$ java -version
openjdk version "11.0.11" 2021-04-20
OpenJDK Runtime Environment AdoptOpenJDK-11.0.11+9 (build 11.0.11+9)
OpenJDK 64-Bit Server VM AdoptOpenJDK-11.0.11+9 (build 11.0.11+9, mixed mode)

Answer 1

应该使用bmsubmit.sh -l来加载一个脚本。
